Documents Incorporated by Reference

Certain information from the Registrants definitive proxy statement for the 2012 Annual Meeting of Shareholders is incorporated herein by reference into Part III hereof.

Mercury General Corporation (Mercury General) and its subsidiaries (referred to herein collectively as the Company) are primarily engaged in writing personal automobile insurance
through 13 insurance subsidiaries (referred to herein collectively as the Insurance Companies) in a number of states, principally California. The Company also writes homeowners, commercial automobile and property, mechanical
breakdown, fire, and umbrella insurance. The direct premiums written for the years ended December 31, 2011, 2010, and 2009 by state and line of business were:

The Company offers automobile policyholders the following types of coverage:
collision, property damage liability, bodily injury (BI) liability, comprehensive, personal injury protection (PIP), underinsured and uninsured motorist, and other hazards. The Companys published maximum limits of liability for private
passenger automobile insurance are, for BI, $250,000 per person and $500,000 per accident, and for property damage, $250,000 per accident. The combined policy limits may be as high as $1,000,000 for vehicles written under the Companys
commercial automobile program. However, the majority of the Companys automobile policies have liability limits that are equal to or less than $100,000 per person and $300,000 per accident for BI and $50,000 per accident for property
damage.

The principal executive offices of Mercury General are located in Los Angeles, California. The
home office of the Companys California insurance subsidiaries and the Information Technology center are located in Brea, California. The Company also owns office buildings in Rancho Cucamonga and Folsom, California, which are used to
support California operations and future expansion, and in St. Petersburg, Florida and in Oklahoma City, Oklahoma, which house Company employees and several third party tenants. The Company maintains branch offices in a number of locations in
California; Richmond, Virginia; Latham, New York; Bridgewater, New Jersey; Vernon Hills, Illinois; Atlanta, Georgia; and Austin and San Antonio, Texas. The Company has approximately 4,500 employees.

which is the parent company of AIS and PoliSeek.

The Company sells its policies through approximately 6,700 independent agents, of which, over 1,200 are located in each of
California and Florida. The remaining agents are located in Georgia, Illinois, Texas, Oklahoma, New York, New Jersey, Virginia, Pennsylvania, Arizona, Nevada, and Michigan. Over half of the Companys agents in California have
represented the Company for more than ten years. The agents, most of whom also represent one or more competing insurance companies, are independent contractors selected and contracted by the Company. No independent agent accounted for more than
2% of the Companys direct premiums written during 2011, 2010, and 2009.

The Company believes that it
compensates its agents above the industry average. During 2011, total commissions incurred were approximately 16% of net premiums written.

The Companys advertising budget is allocated among television, radio, newspaper, internet, and direct mailing media to provide the best coverage available within targeted media markets. While
the majority of these advertising costs are borne by the Company, a portion of these costs are reimbursed by the Companys independent agents based upon the number of account leads generated by the advertising. The Company believes that its
advertising program is important to create brand awareness and to remain competitive in the current insurance climate. During 2011, net advertising expenditures were $21 million.

Underwriting

The Company sets
its own automobile insurance premium rates, subject to rating regulations issued by the Department of Insurance or similar governmental agency in each state in which it is licensed to operate (DOI). Each state has different rate
approval requirements. See RegulationDepartment of Insurance Oversight.

The Company
offers standard, non-standard, and preferred private passenger automobile insurance. Private passenger automobile policies in force for non-California operations represented approximately 20% of total private passenger automobile policies in
force at December 31, 2011. In addition, the Company offers mechanical breakdown insurance in many states and homeowners insurance in Illinois, Oklahoma, New York, Georgia, Texas, New Jersey, Virginia, and Arizona. The Company expects to
complete its withdrawal from the Florida homeowners market by September 2012.

In California, good
drivers (as defined by the California Insurance Code) accounted for approximately 82% of all California voluntary private passenger automobile policies in force at December 31, 2011, while higher risk categories accounted for
approximately 18%. The private passenger automobile renewal rate in California (the rate of acceptance of offers to renew) averages approximately 96%.

Claims

The Company conducts the
majority of claims processing without the assistance of outside adjusters. The claims staff administer all claims and direct all legal and adjustment aspects of claims processing.

Losses and Loss Adjustment Expenses Reserves and Reserve Development

The Company maintains losses and loss adjustment expenses reserves for both reported and unreported claims. Losses and loss adjustment expenses reserves for reported claims are estimated based upon a
case-by-case evaluation of the type of claim involved and the expected development of such claims. Losses and loss adjustment expenses reserves for unreported claims are determined on the basis of historical information by line of
insurance. Inflation is reflected in the reserving process through analysis of cost trends and review of historical reserve settlement.

The Companys ultimate liability may be greater or less than management
estimates of reported losses and loss adjustment expenses reserves. Reserves are analyzed quarterly by the Companys actuarial consultants using current information on reported claims and a variety of statistical techniques. The
Company does not discount to a present value that portion of losses and loss adjustment expenses reserves expected to be paid in future periods. Federal tax law, however, requires the Company to discount losses and loss adjustment expenses
reserves for federal income tax purposes.

The following table presents the development of losses and loss
adjustment expenses reserves for the period 2001 through 2011. The top section of the table shows the reserves at the balance sheet date, net of reinsurance recoverable, for each of the indicated years. This amount represents the estimated
net losses and loss adjustment expenses for claims arising from the current and all prior years that are unpaid at the balance sheet date, including an estimate for losses that had been incurred but not reported (IBNR) to the
Company. The second section shows the cumulative amounts paid as of successive years with respect to that reserve liability. The third section shows the re-estimated amount of the previously recorded reserves based on experience as of the
end of each succeeding year, including cumulative payments made since the end of the respective year. Estimates change as more information becomes known about the frequency and severity of claims for individual years. The bottom line shows
favorable (unfavorable) development that exists when the original reserve estimates are greater (less) than the re-estimated reserves at December 31, 2011.

In evaluating the cumulative development information in the table, it should be noted that each amount includes the effects of all changes in development amounts for prior periods. This table does
not present accident or policy year development data. Conditions and trends that have affected development of the liability in the past may not necessarily occur in the future. Accordingly, it may not be appropriate to extrapolate future
favorable or unfavorable development based on this table.

Gross Reserves for Losses and Loss Adjustment Expenses-end of year
(1)

The Company experienced unfavorable development of approximately $18 million
on the 2010 and prior accident years loss and loss adjustment expenses reserves due primarily to an increase in the estimated loss severity for accident years 2008 through 2010 California BI losses, an increase in PIP reserves in Florida
resulting from court decisions that were adverse to the insurance industry, and development on 2007 and prior accident year New Jersey BI reserves that settled for more than anticipated. These were partially offset by reductions in estimates for
loss adjustment expenses, particularly for the 2010 accident year, related to the transfer of a higher proportion of litigated claims to house counsel and a reduction in the estimate for Florida sinkhole claims for accident year 2010, resulting from
many of those claims being denied due to the absence of sinkhole activity or structural damage to the houses. See Critical Accounting EstimatesReserves in Item 7. Managements Discussion and Analysis of Financial
Condition and Results of Operations.

For the years 2008 and 2009, the Company experienced unfavorable
development of approximately $8 million and $31 million, respectively, on prior accident years losses and loss adjustment expenses resrves. The unfavorable development is primarily due to an increase in the estimated loss severity for accident
years 2008 and 2009 California BI losses, an increase in PIP reserves in Florida resulting from court decisions that were adverse to the insurance industry, and development on 2007 and prior accident years New Jersey BI reserves that settled for
more than anticipated.

For the years 2005 through 2007, the Company experienced unfavorable development of
approximately $110 million to $164 million on prior accident years losses and loss adjustment expenses reserves. The unfavorable development from these years relates primarily to increases in loss severity estimates and loss adjustment
expense estimates for the California BI coverage as well as increases in the provision for losses in New Jersey and Florida.

For 2004, the unfavorable development relates to an increase in the Companys prior accident years loss estimates for personal automobile insurance in Florida and New Jersey. In addition,
an increase in estimates for loss severity for the 2004 accident year reserves for California and New Jersey automobile lines of business contributed to the deficiencies.

For 2003, the favorable development largely relates to lower inflation than originally expected on the BI coverage
reserves for the California automobile line of insurance. In addition, the Company experienced a reduction in expenditures to outside legal counsel for the defense of personal automobile claims in California. This led to a reduction in the
ultimate expense amount expected to be paid out and therefore favorable development in the reserves at December 31, 2003, partially offset by unfavorable development in the Florida automobile lines of business.

For the years 2001 and 2002, the Companys previously estimated loss reserves produced deficiencies that were
reflected in the subsequent years incurred losses. The Company attributes a large portion of the unfavorable development to increases in the ultimate liability for BI, physical damage, and collision claims over what was originally
estimated. The increases in these losses relate to increased severity over what was originally recorded and were the result of inflationary trends in health care, auto parts, and body shop labor costs.

Statutory Accounting Principles

The Companys results are reported in accordance with GAAP, which differ in some respects from amounts reported under SAP prescribed by insurance regulatory authorities. Some of the significant
differences under GAAP are described below:



Policy acquisition costs such as commissions, premium taxes, and other costs that vary with and are primarily related to the acquisition of new and
renewal insurance contracts, are capitalized and amortized on a pro rata basis over the period in which the related premiums are earned, rather than expensed as incurred, as required by SAP.



Certain assets are included in the consolidated balance sheets whereas, under SAP, such assets are designated as nonadmitted
assets, and charged directly against statutory surplus. These assets

Amounts related to ceded reinsurance are shown gross as prepaid reinsurance premiums and reinsurance recoverables, rather than netted against
unearned premium reserves and losses and loss adjustment expenses reserves, respectively, as required by SAP.



Fixed-maturity securities are reported at fair value rather than at amortized cost, or the lower of amortized cost or fair value, depending on the
specific type of security as required by SAP.



Goodwill is reported as the excess of cost of an acquired entity over the fair value of the underlying assets and assessed periodically for
impairment. Intangible assets are amortized over their useful lives. Under SAP, goodwill is reported as the excess of cost of an acquired entity over the statutory book value and amortized over 10 years. Its carrying value is limited to 10% of
adjusted surplus. Intangible assets are not recognized.



The differing treatment of income and expense items results in a corresponding difference in federal income tax expense. Changes in deferred
income taxes are reflected as an item of income tax benefit or expense, rather than recorded directly to statutory surplus as regards policyholders, as required by SAP. Admittance testing under SAP may result in a charge to unassigned surplus
for non-admitted portions of deferred tax assets. Under GAAP, a valuation allowance may be recorded against the deferred tax assets and reflected as an expense.



Certain assessments paid to regulatory agencies that are recoverable from policyholders in future periods are expensed whereas these amounts are
recorded as receivables under SAP.

Operating Ratios (SAP basis)

Loss and Expense Ratios

Loss and expense ratios are used to interpret the underwriting experience of property and casualty insurance companies. Under SAP, losses and loss adjustment expenses are stated as a percentage of
premiums earned because losses occur over the life of a policy, while underwriting expenses are stated as a percentage of premiums written rather than premiums earned because most underwriting expenses are incurred when policies are written and are
not spread over the policy period. The statutory underwriting profit margin is the extent to which the combined loss and expense ratios are less than 100%. The Insurance Companies loss ratio, expense ratio, combined ratio, and the
private passenger automobile industry combined ratio, on a statutory basis, are shown in the following table. The Insurance Companies ratios include lines of insurance other than private passenger automobile. Since these other lines
represent only 18.4% of premiums written, the Company believes its ratios can be compared to the industry ratios included in the following table.

The following table presents, for the periods indicated, the Insurance Companies statutory ratios of net premiums
written to policyholders surplus. Guidelines established by the National Association of Insurance Commissioners (the NAIC) indicate that this ratio should be no greater than 3 to 1.

Investments

The Companys investments are directed by the Chief Investment Officer under the supervision of the Board of
Directors. The Companys investment strategy emphasizes safety of principal and consistent income generation, within a total return framework. The investment strategy has historically focused on maximizing after-tax yield with a primary
emphasis on maintaining a well diversified, investment grade, fixed income portfolio to support the underlying liabilities and achieve a return on capital and profitable growth. The Company believes that investment yield is maximized by
selecting assets that perform favorably on a long-term basis and by disposing of certain assets to enhance after-tax yield and minimize the potential effect of downgrades and defaults. The Company believes that this strategy maintains the
optimal investment performance necessary to sustain investment income over time. The Companys portfolio management approach utilizes a market risk and asset allocation strategy as the primary basis for the allocation of interest
sensitive, liquid and credit assets as well as for monitoring credit exposure and diversification requirements. Within the ranges set by the asset allocation strategy, tactical investment decisions are made in consideration of prevailing market
conditions.

Tax considerations, including the impact of the alternative minimum tax (AMT), are
important in portfolio management. Changes in loss experience, growth rates, and profitability produce significant changes in the Companys exposure to AMT liability, requiring appropriate shifts in the investment asset mix between taxable
bonds, tax-exempt bonds, and equities in order to maximize after-tax yield. The Company closely monitors the timing and recognition of capital gains and losses to maximize the realization of any deferred tax assets arising from capital
losses. At December 31, 2011, the Company had a capital loss carry forward of approximately $20.3 million.

Fixed maturities and short-term bonds at amortized cost and equities and other short-term investments at cost.

The Company applies the fair value option to all fixed maturity and equity
securities and short-term investments at the time the eligible item is first recognized. For more detailed discussion, see Liquidity and Capital ResourcesInvested Assets in Item 7. Managements Discussion and
Analysis of Financial Condition and Results of Operations and Note 2 of Notes to Consolidated Financial Statements.

At December 31, 2011, 74.0% of the Companys total investment portfolio at fair value and 92.6% of its total fixed maturity investments at fair value were invested in tax-exempt state and
municipal bonds. For more detailed information including credit ratings, see Liquidity and Capital ResourcesPortfolio Composition in Item 7. Managements Discussion and Analysis of Financial Condition and Results of
Operations.

The nominal average maturity of the overall bond portfolio was 11.8 years (10.8 years
including all short-term instruments) at December 31, 2011, and is heavily weighted in investment grade tax-exempt municipal bonds. Fixed maturity investments purchased by the Company typically have call options attached, which further
reduce the duration of the asset as interest rates decline. The call-adjusted average maturity of the overall bond portfolio was 4.5 years (4.1 years including all short-term instruments) related to holdings which are heavily weighted with high
coupon issues that are expected to be called prior to maturity. The modified duration of the overall bond portfolio reflecting anticipated early calls was 3.7 years (3.3 years including all short-term instruments) at December 31, 2011,
including collateralized mortgage obligations with a modified duration of 2.4 years and short-term bonds that carry no duration. Modified duration measures the length of time it takes, on average, to receive the present value of all the cash
flows produced by a bond, including reinvestment of interest. As it measures four factors (maturity, coupon rate, yield, and call terms) which determine sensitivity to changes in interest rates, modified duration is considered a better indicator of
price volatility than simple maturity alone. The longer the duration, the more sensitive the asset is to market interest rate fluctuations.

Equity holdings consist of non-redeemable preferred stocks, common stocks on which dividend income is partially tax-sheltered by the 70% corporate dividend received deduction, and a partnership interest
in a private credit fund. At year end, 96.2% of short-term investments consisted of highly rated short-duration securities redeemable on a daily or weekly basis. The Company does not have any direct equity investment in subprime lenders.

Effective January 1, 2008, the Company adopted the fair value option with changes in fair value reflected in net realized investment gains or
losses in the consolidated statements of operations.

The Company operates in the highly competitive property and casualty industry subject to competition on pricing, claims
handling, consumer recognition, coverage offered and other product features, customer service, and geographic coverage. Some of the Companys competitors are larger and well-capitalized national companies which have broad distribution networks
of employed or captive agents.

Reputation for customer service and price are the principal means by which the
Company competes with other automobile insurers. In addition, the marketing efforts of independent agents can provide a competitive advantage. Based on the most recent regularly published statistical compilations of premiums written in 2011, the
Company was the fifth largest writer of private passenger automobile insurance in California and the twelfth largest in the United States.

The property and casualty insurance industry is highly cyclical, with alternating hard and soft market conditions. The Company has historically seen significant premium growth during hard markets. Premium
growth rates in soft markets have ranged from slightly positive to negative and were consistent in 2011.

Reinsurance

The Company has reinsurance through the Florida Hurricane Catastrophe Trust Fund (FHCF) that provides coverage equal to approximately 90 percent of $25 million in excess of $10 million per
occurrence based on the latest information provided by FHCF. The coverage is expected to change when new information is available in March 2012.

For California homeowners policies, the Company has reduced its catastrophe exposure from earthquakes by placing earthquake risks with the California Earthquake Authority (CEA). However,
the Company continues to have catastrophe exposure to fires following an earthquake. For more detailed discussion, see RegulationInsurance Assessments.

The Company carries a commercial umbrella reinsurance treaty and seeks facultative arrangements for large property risks.
In addition, the Company has other reinsurance in force that is not material to the consolidated financial statements. If any reinsurers are unable to perform their obligations under a reinsurance treaty, the Company will be required, as primary
insurer, to discharge all obligations to its insured in their entirety.

Regulation

The Insurance Companies are subject to significant regulation and supervision by insurance departments of the
jurisdictions in which they are domiciled or licensed to operate business.

Department of Insurance Oversight

The powers of the DOI in each state primarily include the prior approval of insurance rates and rating
factors and the establishment of capital and surplus requirements, solvency standards, restrictions on dividend payments and transactions with affiliates. DOI regulations and supervision are designed principally to benefit policyholders rather
than shareholders.

California Proposition 103 requires that property and casualty insurance rates be approved
by the California DOI prior to their use and that no rate be approved which is excessive, inadequate, unfairly discriminatory, or otherwise in violation of the provisions of the initiative. The proposition specifies four statutory factors
required to be applied in decreasing order of importance in determining rates for private passenger automobile insurance: (1) the insureds driving safety record, (2) the number of miles the insured drives annually,
(3) the number of years of driving experience of the insured and (4) whatever optional factors are determined by the California DOI to have a substantial relationship to risk of loss and are adopted by regulation. The statute further

provides that insurers are required to give at least a 20% discount to good drivers, as defined, from rates that would otherwise be charged to such drivers and that no insurer may
refuse to insure a good driver. The Companys rate plan operates under these rating factor regulations.

The Company recently received approval from the California DOI to implement a revenue neutral personal automobile class plan filing. The Company expects the plan will improve the pricing structure to
better align premium rates charged with risks insured. The new plan results in decreased rates for some risks and increased rates for others. As a result, the Company may experience a short-term decrease in the level of policies renewed. Preliminary
indications are that policy renewals have only decreased slightly; however, it is currently unknown what the full extent, if any, of the possible decrease will be. The plan was implemented in December 2011 and is expected to make the Company more
competitive in attracting new personal automobile insurance business.

Insurance rates in Georgia, New York,
New Jersey, Pennsylvania, and Nevada require prior approval from the state DOI, while insurance rates in Illinois, Texas, Virginia, Arizona, and Michigan must only be filed with the respective DOI before they are implemented. Oklahoma and
Florida have a modified version of prior approval laws. In all states, the insurance code provides that rates must not be excessive, inadequate, or unfairly discriminatory.

The DOI in each state in which the Company operates is responsible for conducting periodic financial and market conduct examinations of
the Insurance Companies in their states. Market conduct examinations typically review compliance with insurance statutes and regulations with respect to rating, underwriting, claims handling, billing, and other practices. The following table
presents a summary of current financial and market conduct examinations:

For discussion of current regulatory matters in California, see Regulatory and Legal Matters in Item 7. Managements Discussion and Analysis of Financial Condition and Results of
Operations.

The operations of the Company are dependent on the laws of the states in which it does
business and changes in those laws can materially affect the revenue and expenses of the Company. The Company retains its own legislative advocates in California. The Company made direct financial contributions of $32,150 and $133,350 to
officeholders and candidates in 2011 and 2010, respectively. The Company believes in supporting the political process and intends to continue to make such contributions in amounts which it determines to be appropriate.

Risk-Based Capital

The Insurance Companies must comply with minimum capital requirements under applicable state laws and regulations, and must have adequate reserves for claims. The minimum statutory capital requirements
differ by state and are generally based on balances established by statute, a percentage of annualized premiums, a percentage of annualized loss, or risk-based capital (RBC) requirements. The RBC requirements are based on guidelines
established by the NAIC. The RBC formula was designed to capture the widely varying elements of

risks undertaken by writers of different lines of insurance having differing risk characteristics, as well as writers of similar lines where differences in risk may be related to corporate
structure, investment policies, reinsurance arrangements, and a number of other factors. At December 31, 2011, each of the Insurance Companies had sufficient capital to exceed the highest level of minimum required capital.

Insurance Assessments

The California Insurance Guarantee Association (CIGA) was created to pay claims on behalf of insolvent property and casualty insurers. Each year, these claims are estimated by CIGA and
the Company is assessed for its pro-rata share based on prior year California premiums written in the particular line. These assessments are limited to 2% of premiums written in the preceding year and are recouped through a mandated surcharge
to policyholders in the year after the assessment. There were no CIGA assessments in 2011.

During 2011,
the Company paid $1.8 million in assessments to the New Jersey Unsatisfied Claim and Judgment Fund and the New Jersey Property-Liability Insurance Guaranty Association for assessments relating to its personal automobile line of insurance. As
permitted by state law, the New Jersey assessments paid during 2011 are recoupable through a surcharge to policyholders. The Company recouped a portion of these assessments in 2011 and expects to continue to recoup them in the future. It
is possible that there will be additional assessments in 2012.

The CEA is a quasi-governmental organization
that was established to provide a market for earthquake coverage to California homeowners. The Company places all new and renewal earthquake coverage offered with its homeowner policy through the CEA. The Company receives a small fee for
placing business with the CEA, which is recorded as other revenue in the consolidated statements of operations. Upon the occurrence of a major seismic event, the CEA has the ability to assess participating companies for losses. These
assessments are made after CEA capital has been expended and are based upon each companys participation percentage multiplied by the amount of the total assessment. Based upon the most recent information provided by the CEA, the
Companys maximum total exposure to CEA assessments at April 1, 2011, the most recent date at which information was available, was $55.8 million.

The Insurance Companies in other states are also subject to the provisions of similar insurance guaranty associations. There were no material assessment payments during 2011 in other states.

Holding Company Act

The California Companies are subject to California DOI regulation pursuant to the provisions of the California Insurance Holding Company System Regulatory Act (the Holding Company
Act). The California DOI may examine the affairs of each of the California Companies at any time. The Holding Company Act requires disclosure of any material transactions among affiliates within a Holding Company System. Some
transactions and dividends defined to be of an extraordinary type may not be affected if the California DOI disapproves the transaction within 30 days after notice. Such transactions include, but are not limited to, extraordinary
dividends; management agreements, service contracts, and cost-sharing arrangements; all guarantees that are not quantifiable; derivative transactions or series of derivative transactions; certain reinsurance transactions or modifications thereof in
which the reinsurance premium or a change in the insurers liabilities equals or exceeds 5 percent of the policyholders surplus as of the preceding December 31; sales, purchases, exchanges, loans, and extensions of credit; and
investments, in the net aggregate, involving more than the lesser of 3% of the respective California Companies admitted assets or 25% of statutory surplus as regards policyholders as of the preceding December 31. An extraordinary dividend
is a dividend which, together with other dividends or distributions made within the preceding 12 months, exceeds the greater of 10% of the insurance companys statutory policyholders surplus as of the preceding December 31 or the
insurance companys statutory net income for the preceding calendar year.

An insurance company is also required to notify the California DOI of any
dividend after declaration, but prior to payment. There are similar limitations imposed by other states on the Insurance Companies ability to pay dividends. As of December 31, 2011, the Insurance Companies are permitted to pay
in 2012, without obtaining DOI approval for extraordinary dividends, $178.7 million in dividends, of which $159.3 million would be payable from the California Companies.

The Holding Company Act also provides that the acquisition or change of control of a California domiciled
insurance company or of any person who controls such an insurance company cannot be consummated without the prior approval of the California DOI. In general, a presumption of control arises from the ownership of voting securities
and securities that are convertible into voting securities, which in the aggregate constitute 10% or more of the voting securities of a California insurance company or of a person that controls a California insurance company, such as Mercury
General. A person seeking to acquire control, directly or indirectly, of the Company must generally file with the California DOI
an application for change of control containing certain information required by statute and
published regulations and provide a copy of the application to the Company. The Holding Company Act also effectively restricts the Company from consummating certain reorganizations or mergers without prior regulatory approval.

Each of the Insurance Companies is subject to holding company regulations in the state in which it is domiciled. These
provisions are substantially similar to those of the Holding Company Act.

Assigned Risks

Automobile liability insurers in California are required to sell BI liability, property damage liability, medical expense,
and uninsured motorist coverage to a proportionate number (based on the insurers share of the California automobile casualty insurance market) of those drivers applying for placement as assigned risks. Drivers seek placement
as assigned risks because their driving records or other relevant characteristics, as defined by Proposition 103, make them difficult to insure in the voluntary market. In 2011, assigned risks represented less than 0.1% of total automobile
direct premiums written and less than 0.1% of total automobile direct premium earned. The Company attributes the low level of assignments to the competitive voluntary market. Many of the other states in which the Company conducts business
offer programs similar to that of California. These programs are not a significant contributor to the business written in those states.

Item 1A.

Risk Factors

The Companys business involves various risks and uncertainties in addition to the normal risks of business, some of which are discussed in this section. It should be noted that the Companys
business and that of other insurers may be adversely affected by a downturn in general economic conditions and other forces beyond the Companys control. In addition, other risks and uncertainties not presently known or that the Company
currently believes to be immaterial may also adversely affect the Companys business. If any such risks or uncertainties, or any of the following risks or uncertainties, develop into actual events, there could be a materially adverse effect on
the Companys business, financial condition, results of operations, or liquidity.

The information
discussed below should be considered carefully with the other information contained in this Annual Report on Form 10-K and the other documents and materials filed by the Company with the SEC, as well as news releases and other information publicly
disseminated by the Company from time to time.

Risks Related to the Companys Business

The Company remains highly dependent upon California and several other key states to produce revenues and operating
profits.

For the year ended December 31, 2011, the Company generated 76.2% of its direct
automobile insurance premiums written in California, 8.3% in Florida, 4.0% in New Jersey, and 3.1% in Texas. The Companys financial results are subject to prevailing regulatory, legal, economic, demographic, competitive, and other conditions
in these states and changes in any of these conditions could negatively impact the Companys results of operations.

Mercury General is a holding company that relies on regulated subsidiaries for cash operating profits to satisfy its obligations.

As a holding company, Mercury General maintains no operations that generate revenue sufficient to pay operating expenses,
shareholders dividends, or principal or interest on its indebtedness. Consequently, Mercury General relies on the ability of the Insurance Companies, particularly the California Companies, to pay dividends for Mercury General to meet its
obligations. The ability of the Insurance Companies to pay dividends is regulated by state insurance laws, which limit the amount of, and in certain circumstances may prohibit the payment of, cash dividends. Generally, these insurance regulations
permit the payment of dividends only out of earned surplus in any year which, together with other dividends or distributions made within the preceding 12 months, do not exceed the greater of 10% of statutory surplus as of the end of the preceding
year or the net income for the preceding year, with larger dividends payable only after receipt of prior regulatory approval. The inability of the Insurance Companies to pay dividends in an amount sufficient to enable the Company to meet its cash
requirements at the holding company level could have a material adverse effect on the Companys results of operations, financial condition, and its ability to pay dividends to its shareholders.

The Companys insurance subsidiaries are subject to minimum capital and surplus requirements, and any failure
to meet these requirements could subject the Companys insurance subsidiaries to regulatory action.

The Companys insurance subsidiaries are subject to risk-based capital standards and other minimum capital and
surplus requirements imposed under applicable laws of their state of domicile. The risk-based capital standards, based upon the Risk-Based Capital Model Act adopted by the NAIC, require the Companys insurance

subsidiaries to report their results of RBC calculations to state departments of insurance and the NAIC. If any of the Companys insurance subsidiaries fails to meet these standards and
requirements, the DOI regulating such subsidiary may require specified actions by the subsidiary.

The
Companys success depends on its ability to accurately underwrite risks and to charge adequate premiums to policyholders.

The Companys financial condition, results of operations, and liquidity depend on its ability to underwrite and set premiums accurately for the risks it assumes. Premium rate adequacy is necessary to
generate sufficient premium to offset losses, loss adjustment expenses, and underwriting expenses and to earn a profit. In order to price its products accurately, the Company must collect and properly analyze a substantial volume of data; develop,
test, and apply appropriate rating formulae; closely monitor and timely recognize changes in trends; and project both severity and frequency of losses with reasonable accuracy. The Companys ability to undertake these efforts successfully, and
as a result, price accurately, is subject to a number of risks and uncertainties, including but not limited to:



availability of sufficient reliable data;



incorrect or incomplete analysis of available data;



uncertainties inherent in estimates and assumptions, generally;



selection and application of appropriate rating formulae or other pricing methodologies;



successful innovation of new pricing strategies;



recognition of changes in trends and in the projected severity and frequency of losses;



the Companys ability to forecast renewals of existing policies accurately;



unanticipated court decisions, legislation or regulatory action;



ongoing changes in the Companys claim settlement practices;



changes in operating expenses;



changing driving patterns;



extra-contractual liability arising from bad faith claims;



weather catastrophes, including those which may be related to climate change;

Such risks may result in the Companys pricing being based on outdated, inadequate or inaccurate data, or
inappropriate analyses, assumptions or methodologies, and may cause the Company to estimate incorrectly future changes in the frequency or severity of claims. As a result, the Company could underprice risks, which would negatively affect the
Companys margins, or it could overprice risks, which could reduce the Companys volume and competitiveness. In either event, the Companys financial condition, results of operations, and liquidity could be materially adversely
affected.

The effects of emerging claim and coverage issues on the Companys business are
uncertain and may have an adverse effect on the Companys business.

As industry practices and
legal, judicial, social, and other environmental conditions change, unexpected and unintended issues related to claims and coverage may emerge. These issues may adversely affect the Companys

business by either extending coverage beyond its underwriting intent or by increasing the number or size of claims. In some instances, these changes may not become apparent until sometime after
the Company has issued insurance policies that are affected by the changes. As a result, the full extent of liability under the Companys insurance policies may not be known for many years after a policy is issued.

The Companys insurance rates are subject to prior approval by the departments of insurance in most of the
states in which the Company operates, and to political influences.

In most of the states in which the
Company operates, it must obtain prior approval from the state department of insurance of insurance rates charged to its customers, including any increases in those rates. If the Company is unable to receive approval of the rate changes it requests,
the Companys ability to operate its business in a profitable manner may be limited and its financial condition, results of operations, and liquidity may be adversely affected.

From time to time, the auto insurance industry comes under pressure from state regulators, legislators, and special
interest groups to reduce, freeze, or set rates at levels that do not correspond with underlying costs, in the opinion of the Companys management. The homeowners insurance business faces similar pressure, particularly as regulators in
catastrophe-prone states seek an acceptable methodology to price for catastrophe exposure. In addition, various insurance underwriting and pricing criteria regularly come under attack by regulators, legislators, and special interest groups. The
result could be legislation, regulations, or new interpretations of existing regulations that would adversely affect the Companys business, financial condition, and results of operations.

Loss of, or significant restriction on, the use of credit scoring in the pricing and underwriting of personal lines
products could reduce the Companys future profitability.

The Company uses credit scoring as a
factor in pricing and underwriting decisions where allowed by state law. Some consumer groups and regulators have questioned whether the use of credit scoring unfairly discriminates against some groups of people and are calling to prohibit or
restrict the use of credit scoring in underwriting and pricing. Laws or regulations that significantly curtail or regulate the use of credit scoring, if enacted in a large number of states in which the Company operates, could impact the
Companys future results of operations.

The Company may be unable to refinance its outstanding
debt obligations or obtain sufficient capital to repay the obligations on acceptable terms, or at all.

The Company has an aggregate of $140 million in long-term debt obligations, including a $120 million secured credit
facility that was originally incurred in connection with the AIS acquisition and matures in January 2015; and a $20 million secured bank loan that matures in January 2015.

The Companys ability to repay these debt obligations depends on many factors beyond its control, and the Company
may not generate sufficient cash flow to repay the debt at maturity. The Companys ability to repay or refinance its long term debt at maturity also creates financial risk, particularly if the Companys business or prevailing financial
market conditions are not conducive to refinancing the outstanding debt obligations or obtaining new financing. If the Company is unable to generate sufficient cash flow to repay the debt obligations at maturity or to refinance the obligations on
commercially reasonable terms, the Companys business, financial condition, and results of operations may be harmed.

If the Company cannot maintain its A.M. Best ratings, it may not be able to maintain premium volume in its insurance operations sufficient to attain the Companys financial performance goals.

The Companys ability to retain its existing business or to attract new business in its insurance
operations is affected by its rating by A.M. Best Company. A.M. Best Company currently rates all of the Companys

insurance subsidiaries with sufficient operating history to be rated as either A+ (Superior) or A- (Excellent). If the Company is unable to maintain its A.M. Best ratings, the Company may
not be able to grow its premium volume sufficiently to attain its financial performance goals, and if A.M. Best were to downgrade the Companys ratings, the result may adversely affect the Companys business, financial condition, and
results of operations.

The Company may require additional capital in the future, which may not be
available or may only be available on unfavorable terms.

The Companys future capital
requirements depend on many factors, including its ability to underwrite new business successfully, its ability to establish premium rates and reserves at levels sufficient to cover losses, the success of its current expansion plans and the
performance of its investment portfolio. The Company may need to raise additional funds through equity or debt financing, sales of all or a portion of its investment portfolio or curtail its growth and reduce its assets. Any equity or debt
financing, if available at all, may not be available on terms that are favorable to the Company. In the case of equity financing, the Companys shareholders could experience dilution. In addition, such securities may have rights,
preferences, and privileges that are senior to those of the Companys current shareholders. If the Company cannot obtain adequate capital on favorable terms or at all, its business, financial condition, and results of operations could be
adversely affected.

Funding for the Companys future growth may depend upon obtaining new
financing, which may be difficult to obtain given prevalent economic conditions.

To accommodate the
Companys expected future growth, the Company may require funding in addition to cash provided from current operations. The Companys ability to obtain financing may be constrained by current economic conditions affecting global
financial markets. Specifically, with the recent trends affecting the banking industry, many lenders and institutional investors have ceased funding even the most credit-worthy borrowers. In addition, financial strength and claims-paying
ability ratings have become an increasingly important factor in the Companys ability to access capital markets. Rating agencies assign ratings based upon an evaluation of an insurance companys ability to meet its financial obligations.
The Companys current financial strength rating with Fitch is A+. If the Company were to seek financing through the capital markets in the future, it may need to apply for Standard and Poors and Moodys ratings. The ratings could
limit the Companys access to the capital markets or adversely affect pricing of new debt sought in the capital markets in the future. If the Company is unable to obtain necessary financing, it may be unable to take advantage of opportunities
with potential business partners or new products or to otherwise expand its business as planned.

Changes in market interest rates or defaults may have an adverse effect on the Companys investment portfolio,
which may adversely affect the Companys financial results.

The Companys results are
affected, in part, by the performance of its investment portfolio. The Companys investment portfolio contains interest rate sensitive-investments, such as municipal and corporate bonds. Increases in market interest rates may have an adverse
impact on the value of the investment portfolio by decreasing the value of fixed income securities. Declining market interest rates could have an adverse impact on the Companys investment income as it invests positive cash flows from
operations and as it reinvests proceeds from maturing and called investments in new investments that could yield lower rates than the Companys investments have historically generated. Defaults in the Companys investment portfolio may
produce operating losses and negatively impact the Companys results of operations.

Interest rates are
highly sensitive to many factors, including governmental monetary policies, domestic and international economic and political conditions, and other factors beyond the Companys control. Although the Company takes measures to manage the risks of
investing in a changing interest rate environment, it may not be able to mitigate interest rate sensitivity effectively. The Companys mitigation efforts include maintaining a high quality portfolio and managing the duration of the portfolio to
reduce the effect of interest rate changes. Despite its mitigation efforts, a significant change in interest rates could have a material adverse effect on the Companys financial condition and results of operations.

The Companys valuation of financial instruments may include
methodologies, estimations, and assumptions that are subject to differing interpretations and could result in changes to valuations that may materially adversely affect the Companys financial condition or results of operations.

The Company employs a fair value hierarchy that prioritizes the inputs to valuation techniques used to
measure fair value. The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date using the exit price.
Accordingly, when market observable data is not readily available, the Companys own assumptions are set to reflect those that market participants would be presumed to use in pricing the asset or liability at the measurement date. Assets and
liabilities recorded on the consolidated balance sheets at fair value are categorized based on the level of judgment associated with the input used to measure their fair value and the level of market price observability.

During periods of market disruption, including periods of significantly changing interest rates, rapidly widening credit
spreads, inactivity or illiquidity, it may be difficult to value certain of the Companys securities if trading becomes less frequent and/or market data becomes less observable. There may be certain asset classes in historically active markets
with significant observable data that become illiquid due to changes in the financial environment. In such cases, the valuations associated with such securities may rely more on management judgment and include inputs and assumptions that are less
observable or require greater estimation as well as valuation methods, which are more sophisticated or require greater estimation. The valuations generated by such methods may be different from the value at which the investments ultimately may be
sold. Further, rapidly changing and unprecedented credit and equity market conditions could materially impact the valuation of securities as reported within the Companys financial statements, and the period-to-period changes in value could
vary significantly. Decreases in value may have a material adverse effect on the Companys financial condition or results of operations.

Changes in the financial strength ratings of financial guaranty insurers issuing policies on bonds held in the Companys investment portfolio may have an adverse effect on the Companys
investment results.

In an effort to enhance the bond rating applicable to certain bond issues, some
bond issuers purchase municipal bond insurance policies from private insurers. The insurance generally guarantees the payment of principal and interest on a bond issue if the issuer defaults. By purchasing the insurance, the financial strength
ratings applicable to the bonds are based on the credit worthiness of the insurer as well as the underlying credit of the bond issuer. Several financial guaranty insurers that have issued insurance policies covering bonds held by the Company have
experienced financial strength rating downgrades due to risk exposures on insurance policies that guarantee mortgage debt and related structured products. These financial guaranty insurers are subject to DOI oversight. As the financial
strength ratings of these insurers are reduced, the ratings of the insured bond issues correspondingly decrease. Although the Company has determined that the financial strength rating of the underlying bond issues in its investment portfolio
are within the Companys investment policy without the enhancement provided by the insurance policies, any further downgrades in the financial strength ratings of these insurance companies or any defaults on the insurance policies written by
these insurance companies may reduce the fair value of the underlying bond issues and the Companys investment portfolio or may reduce the investment results generated by the Companys investment portfolio, which could have a material
adverse effect on the Companys financial condition, results of operations, and liquidity.

Deterioration of the municipal bond market in general or of specific municipal bonds held by the Company may result
in a material adverse effect on the Companys financial condition, results of operations, and liquidity.

At December 31, 2011, 74.0% of the Companys total investment portfolio at fair value and 92.6% of its total fixed maturity investments at fair value were invested in tax-exempt municipal
bonds. With such a large percentage of the Companys investment portfolio invested in municipal bonds, the performance of the

Companys investment portfolio, including the cash flows generated by the investment portfolio is significantly dependent on the performance of municipal bonds. If the value of
municipal bond markets in general or any of the Companys municipal bond holdings deteriorate, the performance of the Companys investment portfolio, financial condition, results of operations, and liquidity may be materially and adversely
affected.

If the Companys loss reserves are inadequate, its business and financial position could
be harmed.

The process of establishing property and liability loss reserves is inherently uncertain
due to a number of factors, including underwriting quality, the frequency and amount of covered losses, variations in claims settlement practices, the costs and uncertainty of litigation, and expanding theories of liability. While the Company
believes that its actuarial techniques and databases are sufficient to estimate loss reserves, the Companys approach may prove to be inadequate. If any of these contingencies, many of which are beyond the Companys control, results in
loss reserves that are not sufficient to cover its actual losses, the Companys financial condition, results of operations, and liquidity may be materially adversely affected.

There is uncertainty involved in the availability of reinsurance and the collectability of reinsurance recoverable.

The Company reinsures a portion of its potential losses on the policies it issues to mitigate the
volatility of the losses on its financial condition and results of operations. The availability and cost of reinsurance is subject to market conditions, which are outside of the Companys control. From time to time, market conditions have
limited, and in some cases prevented, insurers from obtaining the types and amounts of reinsurance that they consider adequate for their business needs. As a result, the Company may not be able to successfully purchase reinsurance and transfer a
portion of the Companys risk through reinsurance arrangements. In addition, as is customary, the Company initially pays all claims and seeks to recover the reinsured losses from its reinsurers. Although the Company reports as assets the amount
of claims paid which the Company expects to recover from reinsurers, no assurance can be given that the Company will be able to collect from its reinsurers. If the amounts actually recoverable under the Companys reinsurance treaties are
ultimately determined to be less than the amount it has reported as recoverable, the Company may incur a loss during the period in which that determination is made.

The failure of any of the loss limitation methods employed by the Company could have a material adverse effect on
its financial condition or results of operations.

Various provisions of the Companys policies,
such as limitations or exclusions from coverage which are intended to limit the Companys risks, may not be enforceable in the manner the Company intends. In addition, the Companys policies contain conditions requiring the prompt
reporting of claims and the Companys right to decline coverage in the event of a violation of that condition. While the Companys insurance product exclusions and limitations reduce the Companys loss exposure and help eliminate
known exposures to certain risks, it is possible that a court or regulatory authority could nullify or void an exclusion or legislation could be enacted modifying or barring the use of such endorsements and limitations in a way that would adversely
affect the Companys loss experience, which could have a material adverse effect on its financial condition or results of operations.

The Companys business is vulnerable to significant catastrophic property loss, which could have an adverse effect on its financial condition and results of operations.

The Company faces a significant risk of loss in the ordinary course of its business for property damage resulting from
natural disasters, man-made catastrophes and other catastrophic events, particularly hurricanes, earthquakes, hail storms, explosions, tropical storms, fires, sinkholes, war, acts of terrorism, severe winter weather and other natural and man-made
disasters. Such events typically increase the frequency and severity of automobile and other property claims. Because catastrophic loss events are by their nature unpredictable,

historical results of operations may not be indicative of future results of operations, and the occurrence of claims from catastrophic events may result in substantial volatility in the
Companys financial condition and results of operations from period to period. Although the Company attempts to manage its exposure to such events, the occurrence of one or more major catastrophes in any given period could have a material and
adverse impact on the Companys financial condition and results of operations and could result in substantial outflows of cash as losses are paid.

The Company depends on independent agents who may discontinue sales of its policies at any time.

The Company sells its insurance policies through approximately 6,700 independent agents. The Company must compete with other insurance carriers for these agents business. Some competitors
offer a larger variety of products, lower prices for insurance coverage, higher commissions, or more attractive non-cash incentives. To maintain its relationship with these independent agents, the Company must pay competitive commissions, be
able to respond to their needs quickly and adequately, and create a consistently high level of customer satisfaction. If these independent agents find it preferable to do business with the Companys competitors, it would be difficult to renew
the Companys existing business or attract new business. State regulations may also limit the manner in which the Companys producers are compensated or incentivized. Such developments could negatively impact the Companys
relationship with these parties and ultimately reduce revenues.

The Companys expansion plans may
adversely affect its future profitability.

The Company intends to continue to expand its operations in
several of the states in which the Company has operations and into states in which it has not yet begun operations. The intended expansion will necessitate increased expenditures. The Company expects to fund these expenditures out of cash flow from
operations. The expansion may not occur, or if it does occur may not be successful in providing increased revenues or profitability. If the Companys cash flow from operations is insufficient to cover the increased costs of the expansion, or if
the expansion does not provide the benefits anticipated, the Companys financial condition, results of operations, and ability to grow its business may be harmed.

Any inability of the Company to realize its deferred tax assets may have a material adverse effect on the
Companys financial condition and results of operations.

The Company recognizes deferred tax
assets and liabilities for the future tax consequences related to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and for tax credits. The Company evaluates its
deferred tax assets for recoverability based on available evidence, including assumptions about future profitability and capital gain generation. Although management believes that it is more likely than not that the deferred tax assets will be
realized, some or all of the Companys deferred tax assets could expire unused if the Company is unable to generate taxable income of a sufficient nature in the future sufficient to utilize them.

If the Company determines that it would not be able to realize all or a portion of its deferred tax assets in the future,
the Company would reduce the deferred tax asset through a charge to earnings in the period in which the determination is made. This charge could have a material adverse effect on the Companys results of operations and financial condition. In
addition, the assumptions used to make this determination are subject to change from period to period based on changes in tax laws or variances between the Companys projected operating performance and actual results. As a result, significant
management judgment is required in assessing the possible need for a deferred tax asset valuation allowance. For these reasons and because changes in these assumptions and estimates can materially affect the Companys results of operations and
financial condition, management has included the assessment of a deferred tax asset valuation allowance as a critical accounting estimate.

The carrying value of the Companys goodwill and other intangible
assets could be subject to an impairment write-down.

At December 31, 2011, the Companys
consolidated balance sheet reflected approximately $43 million of goodwill and $54 million of other intangible assets. The Company evaluates whether events or circumstances have occurred that suggest that the fair value of its intangible
assets are below their respective carrying values. The determination that the fair value of the Companys intangible assets is less than its carrying value may result in an impairment write-down. The impairment write-down would be reflected as
expense and could have a material adverse effect on the Companys results of operations during the period in which it recognizes the expense. In the future, the Company may incur impairment charges related to the goodwill and other intangible
assets already recorded or arising out of future acquisitions.

The Company relies on its information
technology systems to manage many aspects of its business, and any failure of these systems to function properly or any interruption in their operation could result in a material adverse effect on the Companys business, financial condition,
and results of operations.

The Company depends on the accuracy, reliability, and proper functioning of
its information technology systems. The Company relies on these information technology systems to effectively manage many aspects of its business, including underwriting, policy acquisition, claims processing and handling, accounting, reserving and
actuarial processes and policies, and to maintain its policyholder data. The Company is developing and deploying new information technology systems that are designed to manage many of these functions across all of the states in which it
operates and all of the lines of insurance it offers. See OverviewTechnology in Item 7. Managements Discussion and Analysis of Financial Condition and Results of Operations. The failure of hardware or
software that supports the Companys information technology systems, the loss of data contained in the systems, or any delay or failure in the full deployment of the Companys new information technology systems could disrupt its business
and could result in decreased premiums, increased overhead costs, and inaccurate reporting, all of which could have a material adverse effect on the Companys business, financial condition, and results of operations.

In addition, despite system redundancy, the implementation of security measures, and the existence of a disaster recovery
plan for the Companys information technology systems, these systems are vulnerable to damage or interruption from:

It is possible that a system failure, accident, or security breach could result in a material disruption to the
Companys business. In addition, substantial costs may be incurred to remedy the damages caused by these disruptions. Following implementation of its new information technology systems, the Company may from time to time install new or upgraded
business management systems. To the extent that a critical system fails or is not properly implemented and the failure cannot be corrected in a timely manner, the Company may experience disruptions to the business that could have a material adverse
effect on the Companys results of operations.

The Companys consolidated financial statements are subject to the application of GAAP, which is periodically revised
and/or expanded. Accordingly, the Company is required to adopt new or revised accounting

standards from time to time issued by recognized authoritative bodies, including the FASB. It is possible that future changes the Company is required to adopt could change the current accounting
treatment that the Company applies to its consolidated financial statements and that such changes could have a material effect on the Companys financial condition and results of operations.

The Company may be required to adopt International Financial Reporting Standards (IFRS). The ultimate
adoption of such standards could negatively impact its financial condition or results of operations.

Although not yet required, the Company could be required to adopt IFRS, which differs from GAAP, for the Companys
accounting and reporting standards. The ultimate implementation and adoption of new standards could materially impact the Companys financial condition or results of operations.

The Companys disclosure controls and procedures may not prevent or detect acts of fraud.

The Companys disclosure controls and procedures are designed to reasonably assure that information required to be
disclosed in reports filed or submitted under the Securities Exchange Act of 1934, as amended, is accumulated and communicated to management and is recorded, processed, summarized and reported within the time periods specified in the SECs
rules and forms. The Companys management, including its Chief Executive Officer and Chief Financial Officer, believe that any disclosure controls and procedures or internal controls and procedures, no matter how well conceived and operated,
can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, the Company cannot provide absolute assurance that all control issues and instances
of fraud, if any, within the Company have been prevented or detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally,
controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by an unauthorized override of the controls. The design of any system of controls also is based in part upon certain assumptions about the
likelihood of future events, and the Company cannot assure that any design will succeed in achieving its stated goals under all potential future conditions. Accordingly, because of the inherent limitations in a cost effective control system,
misstatements due to error or fraud may occur and not be detected.

Failure to maintain an effective
system of internal control over financial reporting may have an adverse effect on the Companys stock price.

Section 404 of the Sarbanes-Oxley Act of 2002, as amended, and the related rules and regulations promulgated by the SEC require the Company to include in its Annual Report on Form 10-K a report by
its management regarding the effectiveness of the Companys internal control over financial reporting. The report includes, among other things, an assessment of the effectiveness of the Companys internal control over financial reporting
as of the end of its fiscal year, including a statement as to whether or not the Companys internal control over financial reporting is effective. This assessment must include disclosure of any material weaknesses in the Companys internal
control over financial reporting identified by management. Areas of the Companys internal control over financial reporting may require improvement from time to time. If management is unable to assert that the Companys internal control
over financial reporting is effective now or in any future period, or if the Companys independent auditors are unable to express an opinion on the effectiveness of those internal controls, investors may lose confidence in the accuracy and
completeness of the Companys financial reports, which could have an adverse effect on the Companys stock price.

The ability of the Company to attract, develop and retain talented employees, managers and executives, and to maintain appropriate staffing levels, is critical to the Companys success.

The Company is constantly hiring and training new employees and seeking to retain current employees.
An inability to attract, retain and motivate the necessary employees for the operation and expansion of the Companys business could hinder its ability to conduct its business activities successfully, develop new products and attract customers.

The Companys success also depends upon the continued contributions of
its executive officers, both individually and as a group. The Companys future performance will be substantially dependent on its ability to retain and motivate its management team. The loss of the services of any of the Companys
executive officers could prevent the Company from successfully implementing its business strategy, which could have a material adverse effect on the Companys business, financial condition, and results of operations.

Challenging economic conditions may negatively affect the Companys business and operating results.

Challenging economic conditions could adversely affect the Company in the form of consumer behavior
and pressure on its investment portfolio. Consumer behavior could include policy cancellations, modifications, or non-renewals, which may reduce cash flows from operations and investments, may harm the Companys financial position, and may
reduce the Insurance Companies statutory surplus. Challenging economic conditions also may impair the ability of the Companys customers to pay premiums as they fall due, and as a result, the Companys bad debt reserves and
write-offs could increase. It is also possible that claims fraud may increase. The recent sovereign debt crisis in Europe is leading to weaker global economic growth, heightened financial vulnerabilities and some negative rating actions. The
Companys investment portfolios could be adversely affected as a result of deteriorating financial and business conditions affecting the issuers of the securities in the Companys investment portfolio. In addition, declines in the
Companys profitability could result in a charge to earnings for the impairment of goodwill, which would not affect the Companys cash flow but could decrease its earnings, and its stock price could be adversely affected.

Many economists believe that the severe economic recession is over but they expect the recovery to be slow with many
businesses feeling the effects of the downturn for years to come. The Company is unable to predict the duration and severity of the current disruption in the financial markets in the United States, and in California, where the majority of the
Companys business is produced. If economic conditions do not show significant improvement, there could be an adverse impact on the Companys financial condition, results of operations, and liquidity.

The Company may be adversely affected if economic conditions result in either inflation or deflation. In an inflationary
environment, established reserves may become inadequate and increase the Companys loss ratio, and market interest rates may rise and reduce the value of the Companys fixed maturity portfolio, while increasing interest expense on its
LIBOR based debt. The DOIs may not approve premium rate increases in time for the Company to adequately mitigate inflated loss costs. In a deflationary environment, some fixed maturity issuers may have difficulty meeting their debt service
obligations and thereby reduce the value of the Companys fixed maturity portfolio; equity investments may decrease in value; and policyholders may experience difficulties paying their premiums to the Company, which could adversely affect
premium revenue.

The presence of defective Chinese-made drywall in homes subject to our homeowner
policies may lead to additional losses and expenses.

Some homeowners in southern Florida have
experienced unpleasant odors and unusual air-conditioning problems, which have been linked to the use of defective Chinese-made drywall. It is difficult to accurately estimate any covered losses that may develop as a result of these problems.
However, if and to the extent the scope of the Chinese-made drywall problems proves to be significant, the Company could incur costs or liabilities related to this issue that could have a material adverse effect on its financial condition, results
of operations, and liquidity.

The Companys business is vulnerable to significant losses related
to sinkhole claims, which could have an adverse effect on its results of operations.

In December 2010,
the Florida Senate issued a 47-page report entitled Issues Relating to Sinkhole Insurance. The report states that the Florida Insurance Commissioner has identified sinkhole claims as a major

cost driver and has expressed concern that such claims could threaten the solvency of domestic insurers and have a destabilizing effect on an already fragile market. While the Company, with
approximately 4,000 homeowners policies in-force in Florida at December 31, 2011, does not believe that the sinkhole issue creates solvency concerns, it does impair profitability. Although the Company expects to complete its withdrawal from the
Florida homeowners market by September 2012, it expects that losses may continue and claims frequency could increase through the completion of the withdrawal.

Risks Related to the Companys Industry

The
private passenger automobile insurance industry is highly competitive, and the Company may not be able to compete effectively against larger, better-capitalized companies.

The Company competes with many property and casualty insurance companies selling private passenger automobile insurance in
the states in which the Company operates. Many of these competitors are better capitalized than the Company and have higher A.M. Best ratings. The superior capitalization of the competitors may enable them to offer lower rates, to withstand larger
losses, and to more effectively take advantage of new marketing opportunities. The Companys competition may also become increasingly better capitalized in the future as the traditional barriers between insurance companies and banks and other
financial institutions erode and as the property and casualty industry continues to consolidate. The Companys ability to compete against these larger, better-capitalized competitors depends on its ability to deliver superior service and its
strong relationships with independent agents.

The Company may undertake strategic marketing and operating
initiatives to improve its competitive position and drive growth. If the Company is unable to successfully implement new strategic initiatives or if the Companys marketing campaigns do not attract new customers, the Companys competitive
position may be harmed, which could adversely affect the Companys business and results of operations. Additionally, in the event of a failure of any competitor, the Company and other insurance companies would likely be required by state law to
absorb the losses of the failed insurer and would be faced with an unexpected surge in new business from the failed insurers former policyholders.

The Company may be adversely affected by changes in the private passenger automobile insurance industry.

81.6% of the Companys direct written premiums for the year ended December 31, 2011 were generated from private
passenger automobile insurance policies. Adverse developments in the market for personal automobile insurance or the personal automobile insurance industry in general, whether related to changes in competition, pricing or regulations, could cause
the Companys results of operations to suffer. The property-casualty insurance industry is also exposed to the risks of severe weather conditions, such as rainstorms, snowstorms, hail and ice storms, hurricanes, tornadoes, wild fires,
sinkholes, earthquakes and, to a lesser degree, explosions, terrorist attacks, and riots. The automobile insurance business is also affected by cost trends that impact profitability. Factors which negatively affect cost trends include inflation in
automobile repair costs, automobile parts costs, used car prices, and medical care.

The Company cannot
predict the impact that changing climate conditions, including legal, regulatory and social responses thereto, may have on its business.

Various scientists, environmentalists, international organizations, regulators and other commentators believe that global climate change has added, and will continue to add, to the unpredictability,
frequency and severity of natural disasters (including, but not limited to, hurricanes, tornadoes, freezes, other storms and fires) in certain parts of the world. In response, a number of legal and regulatory measures and social initiatives have
been introduced in an effort to reduce greenhouse gas and other carbon emissions that may be chief contributors to global climate change. The Company cannot predict the impact that changing climate conditions, if any, will

have on its business or its customers. It is also possible that the legal, regulatory and social responses to climate change could have a negative effect on the Companys results of
operations or financial condition.

The insurance industry is subject to extensive regulation, which may
affect the Companys ability to execute its business plan and grow its business.

The Company is
subject to comprehensive regulation and supervision by government agencies in each of the states in which its insurance subsidiaries are domiciled, sell insurance products, issue policies, or handle claims. Some states impose restrictions or require
prior regulatory approval of specific corporate actions, which may adversely affect the Companys ability to operate, innovate, obtain necessary rate adjustments in a timely manner or grow its business profitably. These regulations provide
safeguards for policyholders and are not intended to protect the interests of shareholders. The Companys ability to comply with these laws and regulations, and to obtain necessary regulatory action in a timely manner is, and will continue to
be, critical to its success. Some of these regulations include:

Required Licensing.
The Company
operates under licenses issued by the DOI in the states in which the Company sells insurance. If a regulatory authority denies or delays granting a new license, the Companys ability to enter that market quickly or offer new insurance products
in that market may be substantially impaired. In addition, if the DOI in any state in which the Company currently operates suspends, non-renews, or revokes an existing license, the Company would not be able to offer affected products in the state.

Transactions Between Insurance Companies and Their Affiliates.
Transactions between the Insurance
Companies and their affiliates (including the Company) generally must be disclosed to state regulators, and prior approval of the applicable regulator is required before any material or extraordinary transaction may be consummated. State regulators
may refuse to approve or delay approval of some transactions, which may adversely affect the Companys ability to innovate or operate efficiently.

Regulation of Insurance Rates and Approval of Policy Forms.
The insurance laws of most states in which the Company conducts business require insurance companies to file insurance rate schedules and
insurance policy forms for review and approval. If, as permitted in some states, the Company begins using new rates before they are approved, it may be required to issue refunds or credits to the Companys policyholders if the new rates are
ultimately deemed excessive or unfair and disapproved by the applicable state regulator. In other states, prior approval of rate changes is required and there may be long delays in the approval process or the rates may not be approved. Accordingly,
the Companys ability to respond to market developments or increased costs in that state can be adversely affected.

Restrictions on Cancellation, Non-Renewal or Withdrawal.
Most of the states in which the Company operates have laws and regulations that limit its ability to exit a market. For example, these
states may limit a private passenger auto insurers ability to cancel and non-renew policies or they may prohibit the Company from withdrawing one or more lines of insurance business from the state unless prior approval is received from the
state insurance department. In some states, these regulations extend to significant reductions in the amount of insurance written, not just to a complete withdrawal. Laws and regulations that limit the Companys ability to cancel and non-renew
policies in some states or locations and that subject withdrawal plans to prior approval requirements may restrict the Companys ability to exit unprofitable markets, which may harm its business and results of operations.

Other Regulations.
The Company must also comply with regulations involving, among other matters:



the use of non-public consumer information and related privacy issues;

periodic financial and market conduct examinations performed by state insurance department examiners; and



the other regulations discussed in this Annual Report on Form 10-K.

The failure to comply with these laws and regulations may also result in regulatory actions, fines and penalties, and in
extreme cases, revocation of the Companys ability to do business in that jurisdiction. In addition, the Company may face individual and class action lawsuits by insured and other parties for alleged violations of certain of these laws or
regulations.

In addition, from time to time, the Company may support or oppose legislation or other
amendments to insurance regulations in California or other states in which it operates. Consequently, the Company may receive negative publicity related to its support or opposition of legislative or regulatory changes that may have a material
adverse effect on the Companys financial condition, results of operations, and liquidity.

Regulation may become more extensive in the future, which may adversely affect the Companys business,
financial condition, and results of operations.

No assurance can be given that states will not make
existing insurance-related laws and regulations more restrictive in the future or enact new restrictive laws. New or more restrictive regulation in any state in which the Company conducts business could make it more expensive for it to continue to
conduct business in these states, restrict the premiums the Company is able to charge or otherwise change the way the Company does business. In such events, the Company may seek to reduce its writings in or to withdraw entirely from these states. In
addition, from time to time, the United States Congress and certain federal agencies investigate the current condition of the insurance industry to determine whether federal regulation is necessary. The Company cannot predict whether and to what
extent new laws and regulations that would affect its business will be adopted, the timing of any such adoption and what effects, if any, they may have on the Companys business, financial condition, and results of operations.

Assessments and other surcharges for guaranty funds, second-injury funds, catastrophe funds, and other mandatory
pooling arrangements may reduce the Companys profitability.

Virtually all states require
insurers licensed to do business in their state to bear a portion of the loss suffered by some insured parties as the result of impaired or insolvent insurance companies. Many states also have laws that established second-injury funds to provide
compensation to injured employees for aggravation of a prior condition or injury which are funded by either assessments based on paid losses or premium surcharge mechanisms. In addition, as a condition to the ability to conduct business in various
states, the insurance subsidiaries must participate in mandatory property and casualty shared market mechanisms or pooling arrangements, which provide various types of insurance coverage to individuals or other entities that otherwise are unable to
purchase that coverage from private insurers. The effect of these assessments and mandatory shared-market mechanisms or changes in them could reduce the Companys profitability in any given period or limit its ability to grow its business.

The insurance industry faces risks related to litigation, which, if
resolved unfavorably, could result in substantial penalties and/or monetary damages, including punitive damages. In addition, insurance companies incur material expenses in the defense of litigation and their results of operations or financial
condition could be adversely affected if they fail to accurately project litigation expenses.

Insurance companies are subject to a variety of legal actions including employee benefit claims, wage and hour claims,
breach of contract actions, tort claims, and fraud and misrepresentation claims. In addition, insurance companies incur and likely will continue to incur potential liability for claims related to the insurance industry in general and the
Companys business in particular, such as claims by policyholders alleging failure to pay for, termination or non-renewal of coverage, interpretation of policy language, sales practices, claims related to reinsurance matters, and other matters.
Such actions can also include allegations of fraud, misrepresentation, and unfair or improper business practices and can include claims for punitive damages.

Court decisions and legislative activity may increase exposures for any of the types of claims insurance companies face. There is a risk that insurance companies could incur substantial legal fees and
expenses, including discovery expenses, in any of the actions companies defend in excess of amounts budgeted for defense.

The Company and its insurance subsidiaries are named as defendants in a number of lawsuits. These lawsuits are described more fully at OverviewB. Regulatory and Legal Matters in
Item 7. Managements Discussion and Analysis of Financial Condition and Results of Operations and Note 17 of Notes to Consolidated Financial Statements. Litigation, by its very nature, is unpredictable and the outcome of these cases
is uncertain. The precise nature of the relief that may be sought or granted in any lawsuit is uncertain and may negatively impact the manner in which the Company conducts its business and results of operations, which could materially increase the
Companys legal expenses. In addition, potential litigation involving new claim, coverage, and business practice issues could adversely affect the Companys business by changing the way policies are priced, extending coverage beyond its
underwriting intent, or increasing the size of claims.

Risks Related to the Companys Stock

The Company is controlled by small number of shareholders who will be able to exert significant influence over
matters requiring shareholder approval, including change of control transactions.

George Joseph and
Gloria Joseph collectively own more than 50% of the Companys common stock. Accordingly, George Joseph and Gloria Joseph have the ability to exert significant influence on the actions the Company may take in the future, including change of
control transactions. This concentration of ownership may conflict with the interests of the Companys other shareholders and lenders.

Future sales of common stock may affect the market price of the Companys common stock and the future exercise of options and warrants will result in dilution to the Companys
shareholders.

The Company may raise capital in the future through the issuance and sale of shares of
its common stock. The Company cannot predict what effect, if any, such future sales will have on the market price of its common stock. Sales of substantial amounts of its common stock in the public market could adversely affect the market price of
the Companys outstanding common stock, and may make it more difficult for shareholders to sell common stock at a time and price that the shareholder deems appropriate. In addition, the Company has issued options to purchase shares of its
common stock. In the event that any options to purchase common stock are exercised, shareholders will suffer dilution in their investment.

Applicable insurance laws may make it difficult to effect a change of control of the Company or the sale of any of its insurance subsidiaries.

Before a person can acquire control of a U.S. insurance company or any holding company of a U.S. insurance company, prior
written approval must be obtained from the DOI of the state where the insurer is

domiciled. Prior to granting approval of an application to acquire control of the insurer or holding company, the state DOI will consider a number of factors relating to the acquirer and the
transaction. These laws and regulations may discourage potential acquisition proposals and may delay, deter or prevent a change of control of the Company or the sale by the Company of any of its insurance subsidiaries, including transactions that
some or all of the Companys shareholders might consider to be desirable.

Although the Company has
consistently paid cash dividends in the past, it may not be able to pay cash dividends in the future.

The Company has paid cash dividends on a consistent basis since the public offering of its common stock in November
1985. However, future cash dividends will depend upon a variety of factors, including the Companys profitability, financial condition, capital needs, future prospects, and other factors deemed relevant by the Board of Directors. The
Companys ability to pay dividends may also be limited by the ability of the Insurance Companies to make distributions to the Company, which may be restricted by financial, regulatory or tax constraints, and by the terms of the
Companys debt instruments. In addition, there can be no assurance that the Company will continue to pay dividends even if the necessary financial and regulatory conditions are met and if sufficient cash is available for distribution.

Properties

The Company owns the following buildings which are mostly occupied by the Companys employees. Space not occupied by
the Company is leased to independent third party tenants. In addition, the Company owns a 4.2 acre parcel of land in Brea, California for future expansion. The Company leases all of its other office space for operations. Office location is not
crucial to the Companys operations, and the Company anticipates no difficulty in extending these leases or obtaining comparable office space. The Companys properties are well maintained, adequately meet its needs, and are being utilized
for their intended purposes.

Legal Proceedings

The Company is, from time to time, named as a defendant in various lawsuits or regulatory actions incidental to its insurance business. The majority of lawsuits brought against the Company relate to
insurance claims that arise in the normal course of business and are reserved for through the reserving process. For a discussion of the Companys reserving methods, see Critical Accounting Estimates in Item 7.
Managements Discussion and Analysis of Financial Condition and Results of Operations and Note 1 of Notes to Consolidated Financial Statements.

The Company also establishes reserves for non-insurance claims related lawsuits, regulatory actions, and other contingencies for which the Company is able to estimate its potential exposure and when the
Company believes a loss is probable. For loss contingencies believed to be reasonably possible, the Company also discloses

the nature of the loss contingency and an estimate of the possible loss, range of loss, or a statement that such an estimate cannot be made. While actual losses may differ from the amounts
recorded and the ultimate outcome of the Companys pending actions is generally not yet determinable, the Company does not believe that the ultimate resolution of currently pending legal or regulatory proceedings, either individually or in the
aggregate, will have a material adverse effect on its financial condition, results of operations, or cash flows.

In all cases, the Company vigorously defends itself unless a reasonable settlement appears appropriate. For a discussion of legal matters, see OverviewB. Regulatory and Legal Matters in
Item 7. Managements Discussion and Analysis of Financial Condition and Results of Operations and Note 17 of Notes to Consolidated Financial Statements, which is incorporated herein by reference.

There are no environmental proceedings arising under federal, state, or local laws or regulations to be discussed.

The closing price of the Companys common stock on February 2, 2012 was $44.29.

Holders

As of February 2, 2012, there were approximately 148 holders of record of the Companys common stock.

Dividends

Since the public offering of its common stock in
November 1985, the Company has paid regular quarterly dividends on its common stock. During 2011 and 2010, the Company paid dividends on its common stock of $2.41 and $2.37 per share, respectively. On February 3, 2012, the Board of
Directors declared a $0.61 quarterly dividend payable on March 29, 2012 to shareholders of record on March 15, 2012.

For financial statement purposes, the Company records dividends on the declaration date. The Company expects to continue the payment of quarterly dividends; however, the continued payment and amount of
cash dividends will depend upon the Companys operating results, overall financial condition, capital requirements, and general business conditions.

Holding Company Act

The California Companies are
subject to California DOI regulation pursuant to the provisions of the Holding Company Act. The Holding Company Act requires disclosure of any material transactions among affiliates within a Holding Company System. Certain transactions and
dividends defined to be of an extraordinary type may not be affected if the California DOI disapproves the transaction within 30 days after notice. An extraordinary dividend is a dividend which, together with other dividends or
distributions made within the preceding 12 months, exceeds the greater of 10% of the insurance companys statutory policyholders surplus as of the preceding December 31 or the insurance companys statutory net income for the
preceding calendar year.

The Insurance Companies are required to notify the California DOI of any dividend
after declaration, but prior to payment. There are similar limitations imposed by other states on the Insurance Companies ability to pay dividends. As of December 31, 2011, the Insurance Companies are permitted to pay in 2012,
without obtaining DOI approval for extraordinary dividends, $178.7 million in dividends to Mercury General, of which $159.3 million is payable from the California Companies.

For a discussion of certain restrictions on the payment of dividends to
Mercury General by some of its insurance subsidiaries, see Note 12 of Notes to Consolidated Financial Statements.

Performance Graph

The following graph compares the cumulative total shareholder returns on the Companys Common Stock
(Symbol: MCY) with the cumulative total returns on the Standard and Poors 500 Composite Stock Price Index (S&P 500 Index) and the Companys industry peer group over the last five years. The graph assumes that $100 was
invested on December 31, 2006 in each of the Companys Common Stock, the S&P 500 Index and the industry peer group and the reinvestment of all dividends.

The Company has had a stock repurchase program since 1998. The Companys Board of Directors authorized a $200 million
stock repurchase on July 30, 2011, and the authorization will expire in June 2012. The Company may repurchase shares of its common stock under the program in open market transactions at the discretion of management. The Company will use
dividends received from the Insurance Companies to fund the share repurchases. Since the inception of the program, the Company has purchased and retired 1,266,100 shares of common stock at an average price of $31.36. No stock has been purchased
since 2000.

Selected Financial Data

The following selected financial and operating data are derived from the Companys audited consolidated financial statements. The selected financial and operating data should be read in conjunction
with Item 7. Managements Discussion and Analysis of Financial Condition and Results of Operations and the consolidated financial statements and notes thereto contained elsewhere in this Annual Report on Form 10-K.

Managements Discussion and Analysis of Financial Condition and Results of Operations

Cautionary Statements

Certain statements in this Annual Report on Form 10-K or in other materials the Company has filed or will file with the SEC (as well as information included in oral statements or other written statements
made or to be made by the Company) contain or may contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as
amended. These forward-looking statements may address, among other things, the Companys strategy for growth, business development, regulatory approvals, market position, expenditures, financial results, and reserves. Forward-looking
statements are not guarantees of performance and are subject to important factors and events that could cause the Companys actual business, prospects and results of operations to differ materially from the historical information contained in
this Annual Report on Form 10-K and from those that may be expressed or implied by the forward-looking statements contained in this Annual Report on Form 10-K and in other reports or public statements made by the Company.

Factors that could cause or contribute to such differences include, among others: the competition currently existing in
the automobile insurance markets in California and the other states in which the Company operates; the cyclical and general competitive nature of the property and casualty insurance industry and general uncertainties regarding loss reserves or other
estimates; the accuracy and adequacy of the Companys pricing methodologies; the Companys success in managing its business in states outside of California; the impact of potential third party bad-faith legislation, changes in
laws, regulations or new interpretations of existing laws and regulations, tax position challenges by the California Franchise Tax Board (FTB), and decisions of courts, regulators and governmental bodies, particularly in California; the
Companys ability to obtain and the timing of the approval of premium rate changes for insurance policies issued in states where the Company operates; the Companys reliance on independent agents to market and distribute its policies; the
investment yields the Company is able to obtain with its investments in comparison to recent yields and the market risks associated with the Companys investment portfolio; the effect government policies may have on market interest rates;
uncertainties related to assumptions and projections generally, inflation and changes in economic conditions; changes in driving patterns and loss trends; acts of war and terrorist activities; court decisions, trends in litigation, and health care
and auto repair costs; adverse weather conditions or natural disasters, including those which may be related to climate change, in the markets served by the Company; the stability of the Companys information technology systems and the ability
of the Company to execute on its information technology initiatives; the Companys ability to realize current deferred tax assets or to hold certain securities with current loss positions to recovery or maturity; and other uncertainties, all of
which are difficult to predict and many of which are beyond the Companys control. GAAP prescribes when a Company may reserve for particular risks including litigation exposures. Accordingly, results for a given reporting period could
be significantly affected if and when a reserve is established for a major contingency. Reported results may therefore appear to be volatile in certain periods.

From time to time, forward-looking statements are also included in the Companys quarterly reports on Form 10-Q and
current reports on Form 8-K, in press releases, in presentations, on its web site, and in other materials released to the public. The Company undertakes no obligation to publicly update any forward-looking statements, whether as a result of new
information or future events or otherwise. Investors are cautioned not to place undue reliance on any forward-looking statements, which speak only as of the date of this Annual Report on Form 10-K or, in the case of any document the Company
incorporates by reference, any other report filed with the SEC or any other public statement made by the Company, the date of the document, report or statement. Investors should also understand that it is not possible to predict or identify all
factors and should not consider the risks set forth above to be a complete statement of all potential risks and uncertainties. If the expectations or assumptions underlying the Companys forward-looking statements prove inaccurate or if
risks or uncertainties arise, actual results could differ materially from those predicted in any forward-looking statements. The factors identified above are believed to be some, but not all, of the important factors that could cause actual
events and results to be significantly different from those that may be expressed or implied in any forward-looking statements.

The operating results of property and casualty
insurance companies are subject to significant quarter-to-quarter and year-to-year fluctuations due to the effect of competition on pricing, the frequency and severity of losses, the effect of weather and natural disasters on losses, general
economic conditions, the general regulatory environment in states in which an insurer operates, state regulation of premium rates, changes in fair value of investments, and other factors such as changes in tax laws. The property and casualty
industry has been highly cyclical, with periods of high premium rates and shortages of underwriting capacity followed by periods of severe price competition and excess capacity. These cycles can have a large impact on the Companys ability to
grow and retain business.

The Company is headquartered in Los Angeles, California and operates primarily as a
personal automobile insurer selling policies through a network of independent agents in thirteen states. The Company also offers homeowners, commercial automobile and property, mechanical breakdown, fire, and umbrella insurance. Private
passenger automobile lines of insurance accounted for 81.6% of the $2.6 billion of the Companys direct premiums written in 2011. 76.7% of the private passenger automobile premiums were written in California. The Company operates
primarily in California, the only state in which it operated prior to 1990. The Company has since expanded its operations into the following states: Georgia and Illinois (1990), Oklahoma and Texas (1996), Florida (1998), Virginia and New York
(2001), New Jersey (2003), and Arizona, Pennsylvania, Michigan, and Nevada (2004).

The Company expects to
continue its growth by expanding into new states in future years with the objective of achieving greater geographic diversification. There are challenges and risks involved in entering each new state, including establishing adequate rates without
any operating history in the state, working with a new regulatory regime, hiring and training competent personnel, building adequate systems, and finding qualified agents to represent the Company. The Company does not expect to enter into any new
states during 2012.

This section discusses some of the relevant factors that management considers in
evaluating the Companys performance, prospects, and risks. It is not all-inclusive and is meant to be read in conjunction with the entirety of managements discussion and analysis, the Companys consolidated financial statements
and notes thereto, and all other items contained within this Annual Report on Form 10-K.

2011 Financial Performance
Summary

The Companys net income for the year ended December 31, 2011 increased to $191.2
million, or $3.49 per diluted share, from $152.2 million, or $2.78 per diluted share, for the same period in 2010. Approximately $141 million in pre-tax investment income was generated during 2011 on a portfolio of approximately $3.1 billion at fair
value at December 31, 2011, compared to $144 million pre-tax investment income during 2010 on a portfolio of approximately $3.2 billion at fair value at December 31, 2010. Included in net income are net realized investment gains of
$58.4 million and $57.1 million in 2011 and 2010, respectively. Net realized investment gains include gains of $31.3 million and $46.6 million in 2011 and 2010, respectively, due to changes in the fair value of total investments pursuant to
application of the fair value accounting option.

During 2011, the Company continued its marketing efforts to
enhance name recognition and lead generation. The Company believes that its marketing efforts, combined with its ability to maintain relatively low prices and a strong reputation, make the Company very competitive in California and in other states.

The Company believes its thorough underwriting process gives it an advantage over competitors. The
Company views its agent relationships and underwriting process as one of its primary competitive advantages because it allows the Company to charge lower rates yet realize better margins than many competitors.

The Companys operating results and growth have allowed it to
consistently generate positive cash flow from operations, which was approximately $159 million and $92 million in 2011 and 2010, respectively. Cash flow from operations has been used to pay shareholder dividends, retire debt, and help support
growth.

Economic and Industry Wide Factors



Regulatory Uncertainty
The insurance industry is subject to strict state regulation and oversight and is governed by the laws of each
state in which each insurance company operates. State regulators generally have substantial power and authority over insurance companies including, in some states, approving rate changes and rating factors, and establishing minimum capital and
surplus requirements. In many states, insurance commissioners may emphasize different agendas or interpret existing regulations differently than previous commissioners. The Company has a successful track record of working with difficult
regulations and new insurance commissioners. However, there is no certainty that current or future regulations and the interpretation of those regulations by insurance commissioners and the courts will not have an adverse impact on the Company.



Cost Uncertainty
Because insurance companies pay claims after premiums are collected, the ultimate cost of an insurance policy is not
known until well after the policy revenues are earned. Consequently, significant assumptions are made when establishing insurance rates and loss reserves. While insurance companies use sophisticated models and experienced actuaries to
assist in setting rates and establishing loss reserves, there can be no assurance that current rates or current reserve estimates will be adequate. Furthermore, there can be no assurance that insurance regulators will approve rate increases
when the Companys actuarial analysis shows that they are needed.



Economic Conditions
Though many businesses are still experiencing the slow recovery from the severe economic recession, the recent
sovereign debt crisis in Europe is leading to weaker global economic growth, heightened financial vulnerabilities and some negative rating actions. The Company is unable to predict the duration and severity of the current disruption in the financial
markets and its impact on the United States, and California, where the majority of the Companys business is produced. If economic conditions do not show improvement, there could be an adverse impact on the Companys financial condition,
results of operations, and liquidity.



Inflation
The largest cost component for automobile insurers is losses, which include medical costs, replacement automobile parts, and
labor costs. There can be significant variation in the overall increases in medical cost inflation, and it is often a year or more after the respective fiscal period ends before sufficient claims have closed for the inflation rate to be known
with a reasonable degree of certainty. Therefore, it can be difficult to establish reserves and set premium rates, particularly when actual inflation rates may be higher or lower than anticipated.



Loss Frequency
Another component of overall loss costs is loss frequency, which is the number of claims per risk insured. There has
been a long-term trend of declining loss frequency in the personal automobile insurance industry. In recent years, the trend has shown increasing loss frequency; however, the Company is unable to predict the trend of loss frequency in the future.



Underwriting Cycle and Competition
The property and casualty insurance industry is highly cyclical, with alternating hard and soft
market conditions. The Company has historically seen significant premium growth during hard markets. Premium growth rates in soft markets have ranged from slightly positive to negative and were consistent in
2011.

Technology

In 2011, the Company continued to enhance its internet agency portal, Mercury First. Mercury First is a single entry point
for agents providing a broad suite of capabilities. One of its most powerful tools is a point of sale (POS) system that allows agents to easily obtain and compare quotes and write new business. Mercury First

is designed as an easy-to-use agency portal that provides a customized work queue for each agency user showing new business leads, underwriting requests and other pertinent customer information
in real time. Agents can also assist customers with processing payments, reporting claims or updating their records. The system enables quick access to documents and forms and empowers the agents with several self-service capabilities.

The NextGen system is designed to be a multi-state, multi-line system. NextGen serves as the primary platform
for all underwriting, billing, claims, and commission functions supporting the private passenger auto line in seven states (Virginia, New York, Florida, California, Georgia, Illinois, and Texas).

During 2010, the Company launched Guidewire, a commercially available software solution, to replace legacy platforms and
implemented it for the Nevada homeowners line. In 2011, the Company expanded the Guidewire implementation to Texas, Georgia, Illinois, Pennsylvania, and Oklahoma for the homeowners line of business and for the Texas commercial auto line of business.
The Company plans to expand Guidewire to other states and lines of business during 2012.

In 2011, as part of
its continuing commitment to service excellence, the Company piloted in Georgia a new web capability for customers to bind and pay for new policies online. These policies will be serviced by the Companys independent agents. The Company plans
to expand this capability to other states in the future.

B. Regulatory and Legal Matters

The process for implementing rate changes varies by state, with California, Georgia, New York, New Jersey, Pennsylvania,
and Nevada requiring prior approval from the respective DOI before a rate may be implemented. Illinois, Texas, Virginia, Arizona, and Michigan only require that rates be filed with the DOI. Oklahoma and Florida have a modified version of prior
approval laws. In all states, the insurance code provides that rates must not be excessive, inadequate, or unfairly discriminatory. For the Companys two largest lines of business, personal automobile and homeowners, the Company filed
rate changes that were neutral in seven states and increases in thirteen states during 2011.

The California
DOI uses rating factor regulations requiring automobile insurance rates to be determined in decreasing order of importance by (1) driving safety record, (2) miles driven per year, (3) years of driving experience, and (4) other
factors as determined by the California DOI to have a substantial relationship to the risk of loss and adopted by regulation.

During 2011, the Company received approval from the California DOI to implement a revenue neutral personal automobile class plan filing. The Company expects the plan will improve the pricing structure to
better align premium rates charged with risks insured. The new plan will lead to decreased rates for some risks and increased rates for others. As a result, the Company may experience a short-term decrease in the number of policies renewed.
Preliminary indications are that policy renewals have only decreased slightly; however, it is currently unknown what the full extent, if any, of the possible decrease will be. The plan was implemented in December 2011 and is expected to make the
Company more competitive in attracting new personal automobile insurance business.

On April 9, 2010, the
California DOI issued a Notice of Non-Compliance (2010 NNC) to MIC, MCC, and CAIC based on a Report of Examination of the Rating and Underwriting Practices of these companies issued by the California DOI on February 18, 2010. The
2010 NNC includes allegations of 35 instances of noncompliance with applicable California insurance law and seeks to require that each of MIC, MCC, and CAIC change its rating and underwriting practices to rectify the alleged noncompliance and may
also seek monetary penalties. On April 30, 2010, the Company submitted a Statement of Compliance and Notice of Defense to the 2010 NNC, in which it denied the allegations contained in the 2010 NNC and provided specific defenses to each
allegation. The Company also requested a hearing in the event that the Statement of Compliance and Notice of Defense does not establish to the satisfaction of the California DOI that the alleged noncompliance does not exist, and the matters

described in the 2010 NNC are not otherwise able to be resolved informally with the California DOI. The California DOI has recently advised the Company that it is continuing to review this matter
and it continues to question certain past practices. No final determination has been made by the California DOI on how it will proceed going forward. The Company anticipates that it will be advised by the California DOI in the near future as to how
the California DOI intends to proceed. The Company denies the allegations in the 2010 NNC and believes that it has done nothing to warrant the penalties cited in the 2010 NNC.

In March 2006, the California DOI issued an Amended Notice of Non-Compliance to a Notice of Non-Compliance originally
issued in February 2004 (as amended, 2004 NNC) alleging that the Company charged rates in violation of the California Insurance Code, willfully permitted its agents to charge broker fees in violation of California law, and willfully
misrepresented the actual price insurance consumers could expect to pay for insurance by the amount of a fee charged by the consumers insurance broker. The California DOI seeks to impose a fine for each policy in which the Company allegedly
permitted an agent to charge a broker fee, which the California DOI contends is the use of an unapproved rate, rating plan or rating system. Further, the California DOI seeks to impose a penalty for each and every date on which the Company allegedly
used a misleading advertisement alleged in the 2004 NNC. Finally, based upon the conduct alleged, the California DOI also contends that the Company acted fraudulently in violation of Section 704(a) of the California Insurance Code, which
permits the California Commissioner of Insurance to suspend certificates of authority for a period of one year. The Company filed a Notice of Defense in response to the 2004 NNC. The Company does not believe that it has done anything to warrant a
monetary penalty from the California DOI. The San Francisco Superior Court, in
Robert Krumme, On Behalf Of The General Public v. Mercury Insurance Company, Mercury Casualty Company, and California Automobile Insurance Company
, denied
plaintiffs requests for restitution or any other form of retrospective monetary relief based on the same facts and legal theory. While this matter has been the subject of multiple continuations since the original Notice of Non-Compliance was
issued in 2004, the Company believes it has received some favorable evidentiary related rulings from the administrative law judge that may impact the outcome of this matter. On June 7, 2011, the Company filed a number of motions, including
motions designed to dispose of the 2004 NNC or to substantially pare it down. Briefing on the motions is complete and the Company has requested oral argument, but no hearing has been set. On January 31, 2012, the administrative law judge issued a
bifurcation order which ordered a separate hearing on the California DOIs order to show cause and accusation, concerning the California DOIs false advertising allegations, to be scheduled after the Commissioners disposition of the
proposed decision on the notice of noncompliance, which concern the California DOIs allegations that Mercury used unlawful rates.

In the 2004 and 2010 NNC matters, the Company believes that no monetary penalties are warranted and intends to defend the issues vigorously. The Company has been subject to fines and penalties by the
California DOI in the past due to alleged violations of the California Insurance Code. The largest and most recent of these was settled in 2008 for $300,000. However, prior settlement amounts are not necessarily indicative of the potential results
in the current Notice of Non-Compliance matters. Based upon its understanding of the facts and the California Insurance Code, the Company does not expect that the ultimate resolution of the 2004 and 2010 NNC matters will be material to the
Companys financial position. The Company has accrued a liability for the estimated cost to defend itself in the regulatory matters described above.

The Company is, from time to time, named as a defendant in various lawsuits or regulatory actions incidental to its insurance business. The majority of lawsuits brought against the Company relate to
insurance claims that arise in the normal course of business and are reserved for through the reserving process. For a discussion of the Companys reserving methods, see Critical Accounting Estimates and Note 1 of Notes to
Consolidated Financial Statements.

The Company also establishes reserves for non-insurance claims related
lawsuits, regulatory actions, and other contingencies for which the Company is able to estimate its potential exposure and when the Company believes a loss is probable. For loss contingencies believed to be reasonably possible, the Company also
discloses the nature of the loss contingency and an estimate of the possible loss, range of loss, or a statement that such an

estimate cannot be made. While actual losses may differ from the amounts recorded and the ultimate outcome of the Companys pending actions is generally not yet determinable, the Company
does not believe that the ultimate resolution of currently pending legal or regulatory proceedings, either individually or in the aggregate, will have a material adverse effect on its financial condition, results of operations, or cash flows.

In all cases, the Company vigorously defends itself unless a reasonable settlement appears appropriate. For a
discussion of legal matters, see Note 17 of Notes to Consolidated Financial StatementsCommitments and ContingenciesLitigation.

C. Critical Accounting Estimates

Reserves

Preparation of the Companys
consolidated financial statements requires judgment and estimates. The most significant is the estimate of loss reserves. Estimating loss reserves is a difficult process as many factors can ultimately affect the final settlement of a claim and,
therefore, the reserve that is required. Changes in the regulatory and legal environment, results of litigation, medical costs, the cost of repair materials, and labor rates, among other factors, can impact ultimate claim costs. In
addition, time can be a critical part of reserving determinations since the longer the span between the incidence of a loss and the payment or settlement of a claim, the more variable the ultimate settlement amount could be. Accordingly,
short-tail claims, such as property damage claims, tend to be more reasonably predictable than long-tail liability claims.

The Company calculates a point estimate rather than a range of loss reserve estimate. There is inherent uncertainty with estimates and this is particularly true with estimates for loss
reserves. This uncertainty comes from many factors which may include changes in claims reporting and settlement patterns, changes in the regulatory or legal environment, uncertainty over inflation rates and uncertainty for unknown
items. The Company does not make specific provisions for these uncertainties, rather it considers them in establishing its reserve by looking at historical patterns and trends and projecting these out to current reserves. The underlying
factors and assumptions that serve as the basis for preparing the reserve estimate include paid and incurred loss development factors, expected average costs per claim, inflation trends, expected loss ratios, industry data, and other relevant
information.

The Company also engages independent actuarial consultants to review the Companys reserves
and to provide the annual actuarial opinions required under state statutory accounting requirements. The Company does not rely on actuarial consultants for GAAP reporting or periodic report disclosure purposes. The Company analyzes loss
reserves quarterly primarily using the incurred loss, claim count, and average severity methods described below. The Company also uses the paid loss development method to analyze loss adjustment expenses reserves as part of its reserve analysis.
When deciding which method to use in estimating its reserves, the Company evaluates the credibility of each method based on the maturity of the data available and the claims settlement practices for each particular line of business or coverage
within a line of business. When establishing the reserve, the Company will generally analyze the results from all of the methods used rather than relying on one method. While these methods are designed to determine the ultimate losses on claims
under the Companys policies, there is inherent uncertainty in all actuarial models since they use historical data to project outcomes. The Company believes that the techniques it uses provide a reasonable basis in estimating loss
reserves.



The
incurred loss development method
analyzes historical incurred case loss (case reserves plus paid losses) development to estimate ultimate
losses. The Company applies development factors against current case incurred losses by accident period to calculate ultimate expected losses. The Company believes that the incurred loss development method provides a reasonable basis for evaluating
ultimate losses, particularly in the Companys larger, more established lines of business which have a long operating history.



The
average severity method
analyzes historical loss payments and/or incurred losses divided by closed claims and/or total claims to
calculate an estimated average cost per claim. From this, the expected

ultimate average cost per claim can be estimated. The
average severity method
coupled with the claim count development method
provide meaningful information regarding inflation and
frequency trends that the Company believes is useful in establishing reserves. The claim count development method analyzes historical claim count development to estimate future incurred claim count development for current claims. The Company applies
these development factors against current claim counts by accident period to calculate ultimate expected claim counts.



The
paid loss development method
analyzes historical payment patterns to estimate the amount of losses yet to be paid. The Company uses this
method for losses and loss adjustment expenses.

The Company analyzes catastrophe losses
separately from non-catastrophe losses. For catastrophe losses, the Company determines claim counts based on claims reported and development expectations from previous catastrophes and applies an average expected loss per claim based on
reserves established by adjusters and average losses on previous similar catastrophes.

There are many factors
that can cause variability between the ultimate expected loss and the actual developed loss. While there are certainly other factors, the Company believes that the following three items tend to create the most variability between expected
losses and actual losses.

(1) Inflation

For the Companys California automobile lines of business, total reserves are comprised of the following:

Loss development on MD reserves is generally insignificant because MD claims are generally settled in a shorter period
than BI reserves. The majority of the loss adjustment expenses reserves are estimated costs to defend BI claims, which tend to require longer periods of time to settle as compared to MD claims.

BI loss reserves are generally the most difficult to estimate because they take longer to close than other coverages. BI
coverage in the Companys policies includes injuries sustained by any person other than the insured, except in the case of uninsured or underinsured motorist BI coverage, which covers damages to the insured for BI caused by uninsured or
underinsured motorists. BI payments are primarily for medical costs and general damages.

The following table
presents the typical closure patterns of BI claims in the California automobile insurance coverage:

% of Total

Claims Closed

Dollars Paid

BI claims closed in the accident year reported

35% to 41%

14%

BI claims closed one year after the accident year reported

75% to 80%

55%

BI claims closed two years after the accident year reported

93% to 95%

83%

BI claims closed three years after the accident year reported

99%

96%

BI claims closed in the accident year reported are generally the smaller and less complex
claims that settle for approximately $2,500 to $3,000, on average, whereas the total average settlement, once all claims are closed in a particular accident year, is approximately $7,500 to $9,000. The Company creates incurred and paid loss
triangles to estimate ultimate losses utilizing historical payment and reserving patterns and evaluates the results of this analysis against its frequency and severity analysis to establish BI reserves. The Company adjusts development factors to
account for inflation trends it sees in loss severity. As a larger proportion of claims from an accident year are settled, there becomes a higher degree of certainty for the reserves established for that

accident year. Consequently, there is a decreasing likelihood of reserve development on any particular accident year, as those periods age. At December 31, 2011, the Company
believes that the accident years that are most likely to develop are the 2009 through 2011 accident years; however, it is possible that older accident years could develop as well.

In general, the Company expects that historical claims trends will continue with costs tending to increase, which is
generally consistent with historical data, and therefore the Company believes that it is more reasonable to expect inflation than deflation. Many potential factors can affect the BI inflation rate, including changes in: claims handling process,
statutes and regulations, the number of litigated files, general economic factors, timeliness of claims adjudication, vehicle safety, weather patterns, and gasoline prices, among other factors; however, the magnitude of such impact on the inflation
rate is unknown.

It is a common practice in the insurance industry for companies to provide small settlement
offers at the inception of a claim to BI claimants who have minor injuries. These claims are settled quickly, reducing the likelihood that BI claimants require larger settlements later on. It also results in some claimants receiving payments that
would not have received any payments if an extended adjudication of the claim had occurred. When a large percentage of the total claims are small dollar value claims resulting from this practice, it has the effect of lowering the total average cost
for all claims (severity) but increasing the total number of claims (frequency). Mercury has historically used this approach to handle its BI claims.

Beginning late in 2008 and continuing through the end of 2009, the Company changed its claims handling procedures and discontinued the practice of providing small settlement offers to BI claimants at the
inception of the claim. This had the effect of increasing loss severity and decreasing loss frequency for the 2009 accident year. The prior practice was reinstated in 2010, which resulted in decreased loss severity and increased loss frequency in
2010 compared to 2009. In 2011, the practice continued with even greater emphasis on settling small claims quickly. As a result, the loss severity comparisons from 2008 through 2011 are impacted, with 2009 showing much higher severities than had
been the trend and 2011 and 2010 showing negative inflation trends when compared to 2010 and 2009. Consequently, the Company believes that inflation trend comparison between 2011 and 2008, when the same claims handling process was practiced, is more
indicative of the actual severity trend. This comparison indicates an annualized inflation trend of 2.4%.

The
Company believes that it is reasonably possible that the California automobile BI severity could vary from recorded amounts by as much as 10%, 7%, and 5% for 2011, 2010, and 2009, respectively. For example, at December 31, 2011, the loss
severity for the amounts recorded at December 31, 2010 increased by 5.2%, 6.8% and 3.8% for the 2010, 2009, and 2008 accident years, respectively. Comparatively, at December 31, 2010, the loss severity decreased for the amount
recorded at December 31, 2009 by 2.6%, 0.8% and 0.1% for the 2009, 2008, and 2007 accident years, respectively. The following table presents the effects on the 2011, 2010, and 2009 accident year California BI loss reserves based on possible
variations in the severity recorded; however, the variation could be more or less than these amounts.

The change in the implied inflation rate in 2010 and 2009 is skewed by the change in claims handling process noted above. The Company believes the
comparison between 2011 and 2008 is more indicative of the actual severity trend. This results in an annualized implied inflation rate of 2.4%.

(2) Claim Count Development

The Company generally
estimates ultimate claim counts for an accident period based on development of claim counts in prior accident periods. For California automobile BI claims, the Company has experienced that approximately 2% to 4% additional claims will be
reported in the year subsequent to an accident year. However, such late reported claims could be more or less than the Companys expectations. Typically, almost every claim is reported within one year following the end of an accident year
and at that point the Company has a high degree of certainty as to what the ultimate claim count will be. The following table presents the number of BI claims reported at the end of the accident period and one year later:

There are many other potential factors that can affect the number of claims reported
after a period end. These factors include changes in weather patterns, a change in the number of litigated files, the number of automobiles insured, and whether the last day of the year falls on a weekday or a weekend. However, the Company is
unable to determine which, if any, of the factors actually impact the number of claims reported and, if so, by what magnitude.

At December 31, 2011, there were 27,977 BI claims reported for the 2011
accident year and the Company estimates that these are expected to ultimately grow by 2.6%. The Company believes that while actual development in recent years has ranged between approximately 2% and 4%, it is reasonable to expect that the range
could be as great as between 0% and 10%. Actual development may be more or less than the expected range. The following table presents the effect on loss development based on different claim count within the broader possible range at

(3) Unexpected Large Losses From Older Accident Periods

Unexpected large losses are generally not provided for in the current reserve because they are not known or expected and
tend to be unquantifiable. Once known, the Company establishes a provision for the losses, but it is not possible to provide any meaningful sensitivity analysis as to the potential size of any unexpected losses. These losses can be caused
by many factors, including unexpected legal interpretations of coverage, ineffective claims handling, regulation extending claims reporting periods, assumption of unexpected or unknown risks, adverse court decisions as well as many unknown factors.

Unexpected large losses are fairly infrequent but can have a large impact on the Companys losses. To
mitigate this risk, the Company has established claims handling and review procedures. However, it is still possible that these procedures will not prove entirely effective, and the Company may have material unexpected large losses in future
periods. It is also possible that the Company has not identified and established a sufficient reserve for all unexpected large losses occurring in the older accident years, even though a comprehensive claims file review was undertaken. The
Company may experience additional development on these reserves.

Discussion of losses and loss reserves and prior period
loss development at December 31, 2011

At December 31, 2011 and 2010, the Company recorded its
point estimate of approximately $985 million and $1,034 million, respectively, in losses and loss adjustment expenses liabilities which include approximately $344 million and $308 million, respectively, of IBNR loss reserves. IBNR includes
estimates, based upon past experience, of ultimate developed costs which may differ from case estimates, unreported claims which occurred on or prior to December 31, 2011 and estimated future payments for reopened claims. Management
believes that the liability for losses and loss adjustment expenses is adequate to cover the ultimate net cost of losses and loss adjustment expenses incurred to date; however, since the provisions are necessarily based upon estimates, the ultimate
liability may be more or less than such provisions.

During 2011, the Company experienced severe losses due to
Georgia tornadoes, Hurricane Irene, and California winter storms occurring between November 30 and December 3, which resulted in increased homeowners and automobile claims. The Company estimates that total losses from these storms are
approximately $18 million.

The Company evaluates its reserves quarterly. When management determines
that the estimated ultimate claim cost requires a decrease for previously reported accident years, favorable development occurs and a reduction in losses and loss adjustment expenses is reported in the current period. If the estimated ultimate claim
cost requires an increase for previously reported accident years, unfavorable development occurs and an increase in losses and loss adjustment expenses is reported in the current period. For 2011, the Company reported unfavorable development of
approximately $18 million on the 2010 and prior accident years losses and loss adjustment expenses reserves which at December 31, 2010 totaled approximately $1.0 billion. The unfavorable development in 2011 is largely the result of
re-estimates of accident years 2008 through 2010 California BI losses which have experienced higher average severities than were originally estimated at December 31, 2010.

Premiums

The Companys insurance premiums are recognized as income ratably over the term of the policies and in proportion to the amount of insurance protection provided. Unearned premiums are carried as a
liability on the balance sheet and are computed on a monthly pro-rata basis. The Company evaluates its unearned premiums periodically for premium deficiencies by comparing the sum of expected claim costs, unamortized acquisition costs, and
maintenance costs partially offset by investment income related to unearned premiums. To the extent that any of the Companys lines of business become substantially unprofitable, a premium deficiency reserve may be required. The Company
established a premium deficiency reserve of $6.0 million for its Florida homeowners operations in 2010. The remaining reserve at December 31, 2011 was $2.5 million. The Company expects to complete its withdrawal from the Florida homeowners market by
September 2012.

Investments

The Companys fixed maturity and equity investments are classified as trading and carried at fair value
as required when applying the fair value option, with changes in fair value reflected in net realized investment gains or losses in the consolidated statements of operations. The majority of equity holdings, including non-redeemable fund preferred
stocks, are actively traded on national exchanges or trading markets, and are valued at the last transaction price on the balance sheet dates.

Fair Value of Financial Instruments

The financial
instruments recorded in the consolidated balance sheets include investments, receivables, interest rate swap agreements, accounts payable, equity contracts, and secured and unsecured notes payable. The fair value of a financial instrument is
the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Due to their short-term maturity, the carrying values of receivables and accounts
payable approximate their fair market values. All investments are carried on the consolidated balance sheets at fair value, as disclosed in Note 1 of Notes to Consolidated Financial Statements.

The Companys financial instruments include securities issued by the U.S. government and its agencies, securities
issued by states and municipal governments and agencies, certain corporate and other debt securities, corporate equity securities, and exchange traded funds. Approximately 98% of the fair value of the financial instruments held at
December 31, 2011 is based on observable market prices, observable market parameters, or is derived from such prices or parameters. The availability of observable market prices and pricing parameters can vary across different financial
instruments. Observable market prices and pricing parameters of a financial instrument, or a related financial instrument, are used to derive a price without requiring significant judgment.

The Company may hold or acquire financial instruments that lack observable market prices or market parameters currently
or in future periods because they are less actively traded. The fair value of such instruments is determined using techniques appropriate for each particular financial instrument. These techniques may

involve some degree of judgment. The price transparency of the particular financial instrument will determine the degree of judgment involved in determining the fair value of the
Companys financial instruments. Price transparency is affected by a wide variety of factors, including, for example, the type of financial instrument, whether it is a new financial instrument and not yet established in the marketplace, and the
characteristics particular to the transaction. Financial instruments for which actively quoted prices or pricing parameters are available or for which fair value is derived from actively quoted prices or pricing parameters will generally have a
higher degree of price transparency. By contrast, financial instruments that are thinly traded or not quoted will generally have diminished price transparency. Even in normally active markets, the price transparency for actively quoted
instruments may be reduced from time to time during periods of market dislocation. Alternatively, in thinly quoted markets, the participation of market makers willing to purchase and sell a financial instrument provides a source of transparency
for products that otherwise is not actively quoted. For a further discussion, see Note 3 of Notes to Consolidated Financial Statements.

Income Taxes

At December 31, 2011, the
Companys deferred income taxes were in a net asset position materially due to unearned premiums, expense accruals, loss reserve discounting, and tax credit carryforward. The Company assesses the likelihood that its deferred tax assets will be
realized and, to the extent management does not believe these assets are more likely than not to be realized, a valuation allowance is established.

Managements recoverability assessment of its deferred tax assets which are ordinary in character takes into consideration the Companys strong history of generating ordinary taxable income and
a reasonable expectation that it will continue to generate ordinary taxable income in the future. Further, the Company has the capacity to recoup its ordinary deferred tax assets through tax loss carryback claims for taxes paid in prior years.
Finally, the Company has various deferred tax liabilities which represent sources of future ordinary taxable income.

Managements recoverability assessment with regard to its capital deferred tax assets is based on estimates of anticipated capital gains and tax-planning strategies available to generate future
taxable capital gains, both of which would contribute to the realization of deferred tax benefits. The Company expects to hold certain quantities of debt securities, which are currently in loss positions, to recovery or maturity. Management believes
unrealized losses related to a significant amount of these debt securities, which represent a portion of the unrealized loss positions at period end, are fully realizable at maturity. The Company has a long-term horizon for holding these securities,
which management believes will allow avoidance of forced sales prior to maturity. The Company also has unrealized gains in its investment portfolio which could be realized through asset dispositions, at managements discretion. Further, the
Company has the capability to generate additional realized capital gains by entering into a sale-leaseback transaction using one or more of its appreciated real estate holdings. Finally, the Company has an established history of generating capital
gain premiums earned through its common stock call option program. Based on the continued existence of the options market, the substantial amount of capital committed to supporting the call option program, and the Companys favorable track
record in generating net capital gains from this program in both upward and downward markets, management believes it will be able to generate sufficient amounts of capital gains from this program, if necessary, to recover recorded capital deferred
tax assets.

The Company has the capability to implement tax planning strategies as it has a steady history of
generating positive cash flow from operations, as well as the reasonable expectation that its cash flow needs can be met in future periods without the forced sale of its investments. This capability assists management in controlling the timing and
amount of realized losses it generates during future periods. By prudent utilization of some or all of these actions, management believes that it has the ability and intent to generate capital gains, and minimize tax losses, in a manner sufficient
to avoid losing the benefits of its deferred tax assets. Management will continue to assess the need for a valuation allowance on a quarterly basis. Although realization is not assured, management believes it is more likely than not that the
Companys deferred tax assets will be realized.

The Companys effective income tax rate can be affected by several
factors. These generally include tax exempt investment income, non-deductible expenses, investment gains and losses, and periodically, non-routine tax items such as adjustments to unrecognized tax benefits related to tax uncertainties. The effective
tax rate for 2011 was 22.0%, compared to 16.6% for 2010. The increase in the effective tax rate is mainly due to an increase in taxable income relative to tax exempt investment income. The Companys effective tax rate for the year ended
December 31, 2011 was lower than the statutory tax rate primarily as a result of tax exempt investment income earned.

Goodwill and Other Intangible Assets

Goodwill and other intangible assets arise as a result of business acquisitions and consist of the excess of the cost of
the acquisitions over the tangible and intangible assets acquired and liabilities assumed and identifiable intangible assets acquired. The Company annually evaluates goodwill and other intangible assets for impairment. The Company also reviews its
goodwill and other intangible assets for impairment whenever events or changes in circumstances indicate that it is more likely than not that the carrying amount of goodwill and other intangible assets may exceed the implied fair value. As of
December 31, 2011, the fair value of the Companys reporting units exceeded their carrying value.

Contingent
Liabilities

The Company has known, and may have unknown, potential liabilities which include claims,
assessments, lawsuits, or regulatory fines and penalties relating to the Companys business. The Company continually evaluates these potential liabilities and accrues for them and/or discloses them in the notes to the consolidated financial
statements where required. The Company does not believe that the ultimate resolution of currently pending legal or regulatory proceedings, either individually or in the aggregate, will have a material adverse effect on its financial condition,
results of operations, or cash flows. See also Regulatory and Legal Matters and Note 17 of Notes to Consolidated Financial Statements.

For a discussion of recently issued accounting standards, see Note 1 of Notes to Consolidated Financial Statements.

RESULTS OF OPERATIONS

Year Ended December 31, 2011 Compared to Year Ended
December 31, 2010

Revenues

Net premiums earned in 2011 were essentially the same as 2010 while net premiums written in 2011 increased by
approximately $20 million from 2010. Net premiums written by the Companys California operations were approximately $2 billion in 2011, a 0.4% decrease from 2010. Net premiums written by the Companys non-California operations
were approximately $632 million in 2011, a 4.5% increase from 2010. Growth outside of California has come as a result of expanded and improved product offerings and higher average premiums per policy.

Net premiums written is a non-GAAP financial measure which represents the premiums charged on policies issued during a
fiscal period less any applicable reinsurance. Net premiums written is a statutory measure designed to determine production levels. Net premiums earned, the most directly comparable GAAP measure, represents the portion of net premiums
written that is recognized as revenue in the financial statements for the period presented and earned on a pro-rata basis over the term of the policies. The following is a reconciliation of total net premiums written to net premiums earned:

Loss and expense ratios are used to interpret the underwriting experience of property and casualty insurance companies.

%

Loss ratio is calculated by dividing losses and loss adjustment expenses by net premiums
earned. The Companys loss ratio for 2011 was generally consistent with the 2010 loss ratio. The loss ratio was affected by unfavorable development of approximately $18 million and favorable development of approximately $13 million on prior
accident years losses and loss adjustment expense reserves for the years ended December 31, 2011 and 2010, respectively. The unfavorable development in 2011 is largely the result of re-estimates of California BI losses which have
experienced higher average severities than originally estimated at December 31, 2010. The 2011 loss ratio was also negatively impacted by severe losses due to California winter storms, Hurricane Irene, and Georgia tornadoes during 2011. The
2010 loss ratio was impacted by severe rainstorms in California and homeowners losses in Florida as a result of sinkhole claims during 2010.

Expense ratio is calculated by dividing the sum of policy acquisition costs plus other operating expenses by net premiums earned. The Companys expense ratio for 2010 was impacted by contributions
made in support of a California legislative initiative totaling $12.1 million and would have been 29.1% without those financial contributions. The 2011 expense ratio decreased as a result of decreased agent contingent commissions, consulting,
advertising, and information technology expenditures.

Combined ratio is the key measure of underwriting
performance traditionally used in the property and casualty insurance industry. A combined ratio under 100% generally reflects profitable underwriting results; and a combined ratio over 100% generally reflects unprofitable underwriting results.

Income tax expenses were $53.9 million and $30.2 million for the years ended December 31, 2011 and 2010,
respectively. The increase in income tax expense resulted from increased taxable income in 2011.

Included in net income are net realized investment gains of $58.4 million
and $57.1 million in 2011 and 2010, respectively. Net realized investment gains include gains of $31.3 million and $46.6 million in 2011 and 2010, respectively, due to changes in the fair value of total investments pursuant to application of the
fair value accounting option. The net gains during 2011 arise from a $62.1 million increase in the market value of the Companys fixed maturity securities offset by a $30.9 million decline in the market value of the Companys equity
securities. The Companys municipal bond holdings represent the majority of the fixed maturity portfolio, which was positively affected by the overall municipal market improvement for 2011. The primary cause of the losses on the Companys
equity securities was the overall decline in the equity markets occurring primarily in the third quarter of 2011.

Net
Income

Net income was $191.2 million or $3.49 per diluted share and $152.2 million or $2.78 per
diluted share in 2011 and 2010, respectively. Diluted per share results were based on a weighted average of 54.8 million shares in 2011 and 2010. Basic per share results were $3.49 and $2.78 in 2011 and 2010,
respectively. Included in net income per share were net realized investment gains, net of income taxes, of $0.69 and $0.68 per share (basic and diluted) in 2011 and 2010, respectively.

Year Ended December 31, 2010 Compared to Year Ended December 31, 2009

Revenues

Net premiums earned and net premiums
written in 2010 decreased 2.2% and 1.3%, respectively, from 2009. Net premiums written by the Companys California operations were approximately $2 billion in 2010, a 3.0% decrease from 2009. Net premiums written by the Companys
non-California operations were approximately $605 million in 2010, a 4.6% increase from 2009. The decrease in net premiums written in California is primarily due to a decrease in the number of policies written and slightly lower average
premiums per policy. Growth outside of California has come as a result of expanded and improved product offerings and higher average premiums per policy.

The Companys loss ratio was affected by favorable development of approximately $13
million and $58 million on prior accident years losses and loss adjustment expenses reserves for the year ended December 31, 2010 and 2009, respectively. The favorable development in 2010 is largely the result of re-estimates of accident

year 2009 California BI losses which have experienced both lower average severities and fewer late reported claims (claim count development) than were originally estimated at December 31,
2009. Excluding the effect of prior accident years loss development, the loss ratios were 71.6% and 70.0% in 2010 and 2009, respectively. The increase is primarily due to severe losses in California from heavy rainstorms in December 2010, and
to sinkhole claims in Florida.

The Companys expense ratio increased primarily due to the decreased net
premiums earned, the Companys financial contributions of $12.1 million related to its support of the Continuous Auto Insurance Discount Act in California, and a premium deficiency reserve of $6.0 million recorded in the Florida homeowners line
of business.

Income tax expenses were $30.2 million and $168.5 million for the years ended December 31,
2010 and 2009, respectively. The decrease in income tax expense resulted primarily from decreased net premium earned, decreased gains on the fair value of the investment portfolio, and increased losses and loss adjustment expenses.

Included in net income are net realized investment gains of $57.1 million and $346.4 million in 2010 and 2009,
respectively. Net realized investment gains include gains of $46.6 million and $395.5 million in 2010 and 2009, respectively, due to changes in the fair value of total investments pursuant to application of the fair value accounting option. The net
gains during 2010 arise from $1.0 million and $45.7 million increases in the market value of the Companys fixed maturity and equity securities, respectively. The primary cause of the gains on the Companys equity securities was the
overall improvement in the equity markets.

Net Income

Net income was $152.2 million or $2.78 per diluted share and $403.1 million or $7.32 per diluted share in 2010 and 2009,
respectively. Diluted per share results were based on a weighted average of 54.8 million shares and 55.1 million shares in 2010 and 2009, respectively. Basic per share results were $2.78 and $7.36 in 2010 and 2009,
respectively. Included in net income per share were net realized investment gains, net of income taxes, of $0.68 and $4.11 per basic share, and $0.68 and $4.09 per diluted share in 2010 and 2009, respectively.

The Company is largely dependent upon dividends received from its insurance subsidiaries to pay debt service costs and to make distributions to its shareholders. Under current insurance law, the
Insurance Companies are entitled to pay ordinary dividends of approximately $179 million in 2012 to Mercury General. The Insurance Companies paid Mercury General extraordinary dividends of $270 million and no ordinary dividends during
2011. As of December 31, 2011, Mercury General had approximately $76 million in investments and cash that could be utilized to satisfy its direct holding company obligations.

The principal sources of funds for the Insurance Companies are premiums, sales and maturity of invested assets, and
dividend and interest income from invested assets. The principal uses of funds for the Insurance Companies are the payment of claims and related expenses, operating expenses, dividends to Mercury General, payment of debt, and the purchase of
investments.

B. Cash Flows

The Company has generated positive cash flow from operations for over twenty consecutive years. Because of the Companys long track record of positive operating cash flows, it does not attempt
to match the duration and timing of asset maturities with those of liabilities. Rather, the Company manages its portfolio with a view towards maximizing total return with an emphasis on after-tax income. With combined cash and short-term
investments of $447.8 million at December 31, 2011, the Company believes its cash flow from operations is adequate to satisfy its liquidity requirements without the forced sale of investments. However, the Company operates in a rapidly
evolving and often unpredictable business environment that may change the timing or amount of expected future cash receipts and expenditures. Accordingly, there can be no assurance that the Companys sources of funds will be sufficient to
meet its liquidity needs or that the Company will not be required to raise additional funds to meet those needs or for future business expansion, through the sale of equity or debt securities or from credit facilities with lending institutions.

Net cash provided by operating activities in 2011 was $158.5 million, an increase of $66.7 million over
2010. The increase was primarily due to the decreased payment of tax and operating expenses. The Company reduced agent contingent commissions, consulting, advertising, and information technology expenditures in 2011. The Company utilized the
cash provided by operating activities primarily for the payment of dividends to its shareholders, the purchase and development of information technology, and the retirement of debt. Funds derived from the sale, redemption or maturity of fixed
maturity investments of $636.2 million were primarily reinvested by the Company in high grade fixed maturity securities.

The following table presents the estimated fair value of fixed maturity securities at December 31, 2011 by contractual maturity in the next five years.

An important component of the
Companys financial results is the return on its investment portfolio. The Companys investment strategy emphasizes safety of principal and consistent income generation, within a total return framework. The investment strategy has
historically focused on maximizing after-tax yield with a primary emphasis on maintaining a well diversified, investment grade, fixed income portfolio to support the underlying liabilities and achieve return on capital and profitable
growth. The Company believes that investment yield is maximized by selecting assets that perform favorably on a long-term basis and by disposing of certain assets to enhance after-tax yield and minimize the potential effect of downgrades and
defaults. The Company continues to believe that this strategy maintains the optimal investment performance necessary to sustain investment income over time. The Companys portfolio management approach utilizes a market risk and
consistent asset allocation strategy as the primary basis for the allocation of interest sensitive, liquid and credit assets as well as for determining overall below investment grade exposure and diversification requirements. Within the ranges set
by the asset allocation strategy, tactical investment decisions are made in consideration of prevailing market conditions.

At December 31, 2011, 74.0% of the Companys total investment portfolio at fair value and 92.6% of its total
fixed maturity investments at fair value were invested in tax-exempt state and municipal bonds. Equity holdings consist of non-redeemable preferred stocks, dividend-bearing common stocks on which dividend income is partially tax-sheltered by the 70%
corporate dividend received deduction, and a partnership interest in a private credit fund. At December 31, 2011, 96.2% of short-term investments consisted of highly rated short-duration securities redeemable on a daily or weekly basis. The
Company does not have any direct investment in subprime lenders.

During 2011, the Company recognized $58.4 million in net realized investment
gains, which include gains of $54.1 million related to fixed maturity securities and losses of $4.9 million related to equity securities. Included in the gains and losses were $62.1 million in gains due to changes in the fair value of the
Companys fixed maturity portfolio and $30.9 million in losses due to changes in the fair value of the Companys equity security portfolio, as a result of applying the fair value option.

During 2010, the Company recognized $57.1 million in net realized investment gains, which include gains of $5.9 million
and $46.5 million related to fixed maturity securities and equity securities, respectively. Included in the gains were $1.0 million and $45.7 million in gains due to changes in the fair value of the Companys fixed maturity portfolio and equity
security portfolio, respectively, as a result of applying the fair value option.

Fixed Maturity Securities

Fixed maturity securities include debt securities, which may have fixed or variable principal payment
schedules, may be held for indefinite periods of time, and may be used as a part of the Companys asset/liability strategy or sold in response to changes in interest rates, anticipated prepayments, risk/reward characteristics, liquidity needs,
tax planning considerations or other economic factors. A primary exposure for the fixed maturity securities is interest rate risk. The longer the duration, the more sensitive the asset is to market interest rate fluctuations. As assets with longer
maturity dates tend to produce higher current yields, the Companys historical investment philosophy has resulted in a portfolio with a moderate duration. The nominal average maturities of the overall bond portfolio were 11.8 years at both
December 31, 2011 and 2010 (10.8 years and 11.3 years, respectively, including all short-term instruments). The portfolio is heavily weighted in investment grade tax-exempt municipal bonds. Fixed maturity investments purchased by the Company
typically have call options attached, which reduce the duration of the asset as interest rates decline. The call-adjusted average maturities of the overall bond portfolio were 4.5 years and 6.3 years (4.1 years and 6.0 years including all short-term
instruments) at December 31, 2011 and 2010, respectively, related to holdings which are heavily weighted with high coupon issues that are expected to be called prior to maturity. The modified durations of the overall bond portfolio reflecting
anticipated early calls were 3.7 years and 4.7 years, (3.3 years and 4.5 years including all short-term instruments), including collateralized mortgage obligations with a modified duration of 2.4 years and 2.2 years at December 31, 2011 and
2010, respectively, and short-term bonds that carry no duration. Modified duration measures the length of time it takes, on average, to receive the present value of all the cash flows produced by a bond, including reinvestment of interest. As it
measures four factors (maturity, coupon rate, yield, and call terms) which determine sensitivity to changes in interest rates, modified duration is considered a better indicator of price volatility than simple maturity alone.

Another exposure related to the fixed maturity securities is credit risk, which is managed by maintaining a
weighted-average portfolio credit quality rating of AA-, at fair value, consistent with the average rating at December 31, 2010. To calculate the weighted-average credit quality ratings as disclosed throughout this Annual Report on Form 10-K,
individual securities were weighted based on fair value and a credit quality numeric score that was assigned to each rating grade. Tax-exempt bond holdings are broadly diversified geographically. Taxable holdings consist principally of investment
grade issues. At December 31, 2011, fixed maturity holdings rated below investment grade and non-rated bonds totaled $95.8 million and $17.2 million, respectively, at fair value, and represented 3.9% and 0.7%, respectively, of total fixed
maturity securities. At December 31, 2010, below investment grade and non-rated fixed maturity holdings totaled $139.4 million and $34.9 million, respectively, at fair value, and represented 5.3% and 1.3%, respectively, of total fixed maturity
securities.

The following table presents the credit quality ratings of the
Companys fixed maturity portfolio by security type at December 31, 2011 at fair value. The Companys estimated credit quality ratings are based on the average of ratings assigned by nationally recognized securities rating
organizations. Credit ratings for the Companys fixed maturity portfolio were stable as compared to the prior year, with 77.6% of fixed maturity securities at fair value experiencing no change in their overall rating. 15.9% of fixed maturity
securities at fair value experienced downgrades during the period, partially offset by 6.5% in credit upgrades. The majority of the downgrades were due to continued downgrading of the monoline insurance carried on much of the municipal holdings. The
majority of the downgrades were slight and the affected securities remain in the investment grade portfolio, except for $3.8 million of fixed maturity securities, at fair value, that were downgraded to below investment grade during 2011.

Intermediate ratings are offered at each level (e.g., AA includes AA+, AA and AA-).

The Company had $32.0 million, 1.3% of its fixed maturity portfolio, at fair
value in U.S. government bonds and agencies and mortgage-backed securities (agencies). In August 2011, Standard and Poors downgraded the U.S. governments long-term sovereign credit rating from AAA to AA+. This downgrade has triggered
significant volatility in prices for a variety of investments. While Moodys and Fitch affirmed their AAA ratings, they placed a negative outlook in November 2011 and warned of a potential downgrade if no long-term deficit agreement was reached
over the next two years. The negative outlook reflects these rating agencies declining confidence that timely fiscal measures will be forthcoming to place U.S. public finances on a sustainable path and secure the AAA ratings. Standard and
Poors affirmed the U.S. Treasurys short-term credit rating of AAA indicating that the short-term capacity of the U.S. to meet its financial commitment on its outstanding obligations is strong. The Company understands that market
participants continue to use rates of return on U.S. government debt as a risk-free rate. In addition, in the period after the downgrade, market participants continued to invest in U.S. Treasury securities and push the yield on U.S. Treasury
securities even lower than before the downgrade.

(1) Municipal Securities

The Company had $2.3 billion at fair value ($2.2 billion at amortized cost) in municipal bonds at December 31, 2011,
of which $1.3 billion were insured by bond insurers. For insured municipal bonds that have underlying ratings, the average underlying rating was A+ at December 31, 2011.

At December 31, 2011, the bond insurers providing credit enhancement were Assured Guaranty Corporation and National
Public Finance Guarantee Corporation, which covered approximately 10% of the insured municipal securities. The average rating of the Companys insured municipal bonds by these bond insurers was A+, with an underlying rating of A-. The remaining
bond insurers credit ratings, which covered approximately 90% of the insured municipal securities, are non-rated or below investment grade, and the Company does not believe that these insurers provide credit enhancement to the municipal bonds
that they insure.

The Company considers the strength of the underlying credit as a buffer against potential
market value declines which may result from future rating downgrades of the bond insurers. In addition, the Company has a long-term time horizon for its municipal bond holdings which generally allows it to recover the full principal amounts upon
maturity and avoid forced sales prior to maturity of bonds that have declined in market value due to the bond insurers rating downgrades. Based on the uncertainty surrounding the financial condition of these insurers, it is possible that there
will be additional downgrades to below investment grade ratings by the rating agencies in the future, and such downgrades could impact the estimated fair value of municipal bonds.

Municipal securities included auction rate securities (ARS). The Company owned $0 and $1.6 million at fair
value of ARS at December 31, 2011 and 2010, respectively. ARS are valued based on a discounted cash flow model with certain inputs that are not observable in the market and are considered Level 3 inputs.

(2) Mortgage-Backed Securities

The mortgage-backed securities portfolio is categorized as loans to prime borrowers except for $9.8 million and $11.5 million ($8.3 million and $10.7 million at amortized cost) of Alt-A
mortgages at December 31, 2011 and 2010, respectively. Alt-A mortgage backed securities are at fixed or variable rates and include certain securities that are collateralized by residential mortgage loans issued to borrowers with stronger credit
profiles than sub-prime borrowers, but do not qualify for prime financing terms due to high loan-to-value ratios or limited supporting documentation. At December 31, 2011, the Company had no holdings in commercial mortgage-backed securities.

The weighted-average rating of the Companys Alt-A mortgage-backed securities was BB+ and the
weighted-average rating of the entire mortgage backed securities portfolio was A+ as of December 31, 2011.

Included in fixed maturity securities are $75.1 million and $95.2 million of fixed rate corporate securities, which had
durations of 3.6 and 4.1 years, at December 31, 2011 and 2010, respectively. The weighted-average rating was BBB+ as of December 31, 2011 and 2010.

(4) Collateralized Debt Obligations

Included in
fixed maturities securities are collateralized debt obligations of $47.5 million and $55.7 million, which represent 1.6% and 1.8% of the total investment portfolio and had durations of 1.1 years and 2.0 years, at December 31, 2011 and 2010,
respectively.

Equity Securities

Equity holdings consist of non-redeemable preferred stocks, common stocks on which dividend income is partially
tax-sheltered by the 70% corporate dividend received deduction, and a partnership interest in a private credit fund. The net losses in 2011 due to changes in fair value of the Companys equity portfolio were $30.9 million. The primary cause of
the losses on the Companys equity securities was the overall decline in the equity markets.

The
Companys common stock allocation is intended to enhance the return of and provide diversification for the total portfolio. At December 31, 2011, 12.4% of the total investment portfolio at fair value was held in equity securities, compared
to 11.4% at December 31, 2010. The following table presents the equity security portfolio by industry sector for 2011 and 2010:

Short-Term Investments

At December 31, 2011, short-term investments include money market accounts, options, and short-term bonds which are
highly rated short duration securities and redeemable within one year.

D. Debt

The Company retired all of its $125 million 7.25% senior notes on the August 15, 2011 maturity date by using a
portion of the proceeds from the extraordinary dividend paid by MCC to Mercury General.

Effective August 4, 2011, the Company extended the maturity date of the
$120 million Bank of America credit facility from January 1, 2012 to January 2, 2015 with interest payable at a floating rate of LIBOR rate plus 40 basis points.

On October 4, 2011, the Company refinanced its Bank of America $18 million LIBOR plus 50 basis points loan that was
scheduled to mature on March 1, 2013 with a Union Bank $20 million LIBOR plus 40 basis points loan that matures on January 2, 2015.

Both the $120 million credit facility and the $20 million bank loan contain financial covenants pertaining to minimum statutory surplus, debt to capital ratio, and risk based capital ratio. The Company is
in compliance with all of its financial covenants.

For a further discussion, see Notes 6 and 7 of Notes to
Consolidated Financial Statements.

E. Capital Expenditures

In 2011, the Company made capital expenditures of approximately $18 million primarily related to Information Technology.

F. Regulatory Capital Requirement

The Insurance Companies must comply with minimum capital requirements under applicable state laws and regulations, and must have adequate reserves for claims. The minimum statutory capital requirements
differ by state and are generally based on balances established by statute, a percentage of annualized premiums, a percentage of annualized loss, or RBC requirements. The RBC requirements are based on guidelines established by the NAIC. The RBC
formula was designed to capture the widely varying elements of risks undertaken by writers of different lines of insurance having differing risk characteristics, as well as writers of similar lines where differences in risk may be related to
corporate structure, investment policies, reinsurance arrangements, and a number of other factors. At December 31, 2011, the Insurance Companies had sufficient capital to exceed the highest level of minimum required capital.

Among other considerations, industry and regulatory guidelines suggest that the ratio of a property and casualty
insurers annual net premiums written to statutory policyholders surplus should not exceed 3.0 to 1. Based on the combined surplus of all the Insurance Companies of $1.5 billion at December 31, 2011, and net premiums written of
$2.6 billion, the ratio of premiums written to surplus was 1.7 to 1.

OFF-BALANCE SHEET ARRANGEMENTS

As of December 31, 2011, the Company had no off-balance sheet arrangements as defined under Regulation S-K 303(a)(4)
and the instructions thereto.

The Companys significant contractual obligations at December 31, 2011 are summarized as follows:

The Companys debt contains various terms, conditions and covenants which, if violated by the Company, would result in a default and could
result in the acceleration of the Companys payment obligations. Amounts differ from the balance presented on the consolidated balance sheets as of December 31, 2011 because the debt amounts above include interest.

(2)

The Company is obligated under various non-cancellable lease agreements providing for office space, automobiles, and office equipment that expire at
various dates through the year 2019.

(3)

Reserve for losses and loss adjustment expenses is an estimate of amounts necessary to settle all outstanding claims, including IBNR as of
December 31, 2011. The Company has estimated the timing of these payments based on its historical experience and expectation of future payment patterns. However, the timing of these payments may vary significantly from the amounts shown above.
The ultimate cost of losses may vary materially from recorded amounts which are the Companys best estimates.

(4)

The table excludes liabilities of $3.6 million related to uncertainty in tax settlements as the Company is unable to reasonably estimate the timing
and amount of related future payments.

Item 7A.

Quantitative and Qualitative Disclosures about Market Risks

The Company is subject to various market risk exposures primarily due to its investing and borrowing
activities. Primary market risk exposures are changes in interest rates, equity prices, and credit risk. Adverse changes to these rates and prices may occur due to changes in the liquidity of a market, or to changes in market perceptions
of creditworthiness and risk tolerance. The following disclosure reflects estimates of future performance and economic conditions. Actual results may differ.

Overview

The Companys investment policies define the
overall framework for managing market and investment risks, including accountability and controls over risk management activities, and specify the investment limits and strategies that are appropriate given the liquidity, surplus, product profile,
and regulatory requirements of the subsidiaries. Executive oversight of investment activities is conducted primarily through the Companys investment committee. The Companys investment committee focuses on strategies to enhance
after-tax yields, mitigate market risks, and optimize capital to improve profitability and returns.

The
Company manages exposures to market risk through the use of asset allocation, duration, and credit ratings. Asset allocation limits place restrictions on the total funds that may be invested within an asset class. Duration limits on the fixed
maturities portfolio place restrictions on the amount of interest rate risk that may be taken. Comprehensive day-to-day management of market risk within defined tolerance ranges occurs as portfolio managers buy and sell within their respective
markets based upon the acceptable boundaries established by investment policies.

Credit risk is due to uncertainty in a counterpartys ability to meet its obligations. Credit risk is managed by maintaining a high credit quality fixed maturities portfolio. As of December 31,
2011, the estimated weighted-average credit quality rating of the fixed maturities portfolio was AA-, at fair value, consistent with the average rating at December 31, 2010. Historically, the ten-year default rate per Moodys for AA rated
municipal bonds has been less than 1%. The Companys municipal bond holdings, which represent 92.9% of its fixed maturity portfolio at December 31, 2011, at fair value, are broadly diversified geographically. 99.7% of municipal bond
holdings are tax-exempt. The following table presents municipal bond holdings by state in descending order of holdings at fair value at December 31, 2011:

The portfolio is broadly diversified among the states and the largest holdings are in
populous states such as Texas and California. These holdings are further diversified primarily among cities, counties, schools, public works, hospitals and state general obligations. Credit risk is addressed by limiting exposure to any
particular issuer to ensure diversification.

Taxable fixed maturity securities represent 7.4% of the
Companys fixed maturity portfolio. 17.8% of the Companys taxable fixed maturity securities were comprised of U.S. government bonds and agencies and mortgage-backed securities (agencies), which were rated AAA at December 31,
2011. 38.3% of the Companys taxable fixed maturity securities, representing 2.8% of the total fixed maturity portfolio, were rated below investment grade. Below investment grade issues are considered watch list items by the
Company, and their status is evaluated within the context of the Companys overall portfolio and its investment policy on an aggregate risk management basis, as well as their ability to recover their investment on an individual issue basis.

Equity price risk

Equity price risk is the risk that the Company will incur losses due to adverse changes in the general levels of the equity markets.

At December 31, 2011, the Companys primary objective for common equity investments is current income. The
fair value of the equity investments consists of $359.0 million in common stocks, $11.4 million in non-redeemable preferred stocks, and $10.0 million in a partnership interest in a private credit fund. Common stock equity assets are typically valued
for future economic prospects as perceived by the market. The Company invests more in the energy and utility sector relative to the S&P 500 Index.

Common stocks represent 11.7% of total investments at fair value. Beta is a measure of a securitys systematic (non-diversifiable) risk, which is the percentage change in an individual
securitys return for a 1% change in the return of the market. The average Beta for the Companys common stock holdings was 1.18 at December 31, 2011. Based on a hypothetical 25% or 50% reduction in the overall value of the
stock market, the Company estimates that the fair value of the common stock portfolio would decrease by $105.9 million or $211.8 million, respectively.

Interest rate risk is the risk that the Company will incur a loss due to adverse changes in interest rates relative to the
interest rate characteristics of interest bearing assets and liabilities. This risk arises from many of its primary activities, as the Company invests substantial funds in interest sensitive assets and issues interest sensitive
liabilities. Interest rate risk includes risks related to changes in U.S. Treasury yields and other key benchmarks, as well as changes in interest rates resulting from the widening credit spreads and credit exposure to collateralized
securities.

The value of the fixed maturity portfolio, which represents 79.9% of total investment at fair
value, is subject to interest rate risk. As market interest rates decrease, the value of the portfolio increases and vice versa. A common measure of the interest sensitivity of fixed maturity assets is modified duration, a calculation that
utilizes maturity, coupon rate, yield and call terms to calculate an average age of the expected cash flows. The longer the duration, the more sensitive the asset is to market interest rate fluctuations.

The Company has historically invested in fixed maturity investments with a goal towards maximizing after-tax yields and
holding assets to the maturity or call date. Since assets with longer maturity dates tend to produce higher current yields, the Companys historical investment philosophy resulted in a portfolio with a moderate duration. Bond
investments made by the Company typically have call options attached, which further reduce the duration of the asset as interest rates decline. The decrease in municipal bond credit spreads in 2011 caused overall interest rates to decrease,
which resulted in the decrease in the duration of the Companys portfolio. Consequently, the modified duration of the bond portfolio reflecting anticipated early calls was 3.7 years at December 31, 2011 compared to 4.7 years and 5.1
years at December 31, 2010 and 2009, respectively. Given a hypothetical parallel increase of 100 or 200 basis points in interest rates, the fair value of the bond portfolio at December 31, 2011 would decrease by $90.8 million or
$181.6 million, respectively.

Interest rate swaps are used to manage interest rate risk associated with the
Companys loans with fixed or floating rates. On February 6, 2009, the Company entered into an interest swap of its floating LIBOR rate on the $120 million credit facility for a fixed rate of 1.93% that expired in January 2012. On
March 3, 2008, the Company entered into an interest rate swap of a floating LIBOR rate on an $18 million bank loan for a fixed rate of 3.75% that expires in March 2013. Effective January 2, 2002, the Company entered into an interest rate
swap of a 7.25% fixed rate obligation on its $125 million senior note for a floating rate of LIBOR plus 107 basis points. The Company retired all of its $125 million 7.25% senior notes on the August 15, 2011 maturity date. The related interest
rate swap agreement expired concurrently.

We have audited the accompanying
consolidated balance sheets of Mercury General Corporation and subsidiaries as of December 31, 2011 and 2010, and the related consolidated statements of operations, comprehensive income, shareholders equity, and cash flows for each
of the years in the three-year period ended December 31, 2011. These consolidated financial statements are the responsibility of the Companys management. Our responsibility is to express an opinion on these consolidated financial
statements based on our audits.

We conducted our audits in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our
opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Mercury General Corporation and subsidiaries as of December 31, 2011 and 2010, and the results of their
operations and their cash flows for each of the years in the three-year period ended December 31, 2011, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States),
Mercury General Corporations internal control over financial reporting as of December 31, 2011, based on criteria established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the
Treadway Commission (COSO), and our report dated February 13, 2012 expressed an unqualified opinion on the effectiveness of the Companys internal control over financial reporting.
